Question

A larval stage occurs in the life history of all members of the group
A. Frog, lizard and cockroach
B. Ascaris, cockroach and frog
C. Housefly, earthworm and mosquito
D. Butterfly, frog and mosquito

Answer 1

A larva is a particular adolescent structure numerous creatures go through before transformation into grown-ups. Creatures with indirect development, for example, insects, amphibians, or cnidarians commonly have a larval period of their life cycle.The larva's appearance is commonly totally different from the grown-up structure (for example caterpillars and butterflies) including diverse one of a kind structures and organs that don't happen in the grown-up structure. Their eating routine may likewise be extensively unique.

Complete answer:
Butterfly larva are really what we call caterpillars. Caterpillars don't remain in this stage for long and generally, in this stage everything they do is eat. At the point when the egg incubates, the caterpillar will begin his work and eat the leaf they were conceived onto. This is truly significant on the grounds that the mother butterfly needs to lay her eggs on the kind of leaf the caterpillar will eat – every caterpillar type prefers just particular sorts of leaves. Since they are small and can not head out to another plant, the caterpillar needs to bring forth on the sort of leaf it needs to eat. Caterpillars need to eat and eat so they can develop rapidly. At the point when a caterpillar is conceived, they are tiny. At the point when they begin eating, they right away begin developing and extending. Their exoskeleton (skin) doesn't extend or develop, so they develop by "shedding" (shedding the grown out of skin) a few times while it develops.
In case of mosquito ,Larvae rise up out of mosquito eggs, however simply after the water level ascents to cover the eggs. This implies that water or people adding water to holders with eggs will trigger the larva to develop. Larvae feed on microorganisms in the water. Subsequent to shedding multiple times, the larva turns into a pupa.
In case of frogs, when the tadpole hatches, it looks more like a fish than a frog. It doesn't have any legs! It has gills that permit it to inhale submerged. The tadpole swims, eats plants and green growth from the water, and develops for a little while. During this time, the tadpole begins to create lungs so it will have the option to inhale out of the water when it turns into a frog. The tadpole likewise begins to grow two rear legs. Presently it can jump around rather than just swimming. In spite of the fact that the tadpole is beginning to look somewhat more like a frog, it actually has an exceptionally long tail!

So, the correct answer is option D.

Note:
Butterfly, frog and mosquito every one of the three have larval stages.

The caterpillar is the larval phase of a butterfly.
The tadpole is the larval phase of frog and mosquitoes additionally have larval stage which is oceanic.
Butterfly,mosquito and housefly go through complete transformation i.e., they have four phases of development as egg, hatchling, pupa and grown-up. The larva of the butterfly is caterpillar,that of mosquito is wriggler while that of a housefly is a maggot.
