B.Leaves are absent
C.Leaves are swollen
D.Leaves modified to reduce transpiration

Answer 1

Some succulent plants have spines which are modified leaves.

Complete answer:
Lithops plant is one of a couple of plants that not just mixes in with a specific stone arrangement yet in addition embraces the stone's tone and surface. The Lithops plant is known as the rock plant or living stone.
Lithops is a class of delicious plants in the ice plant family, Aizoaceae. They abstain from being eaten by mixing in with encompassing rocks and are frequently known as rock plants or living stones. These are little delicious plants that get by in their cruel climate by having a great part of the plant body subterranean. Every individual plant comprises two delicious leaves intertwined looking like an altered cone (albeit a few animal varieties will create multi-headed plants). The crevice at the head of the plant is the division between the two leaves and is spine-like.
So, the right option is (A) leaves modified to spines.
Additional Information: The rock plant monitors water by melding two leaves to frame a circle. This is a development that impersonates the surface zone presented to the sun, while boosting the volume. These leaves pack in a great deal of dampness and sugars. This permits the plant to endure days in dry conditions.

Hence the correct answer is OPTION(A)

Note: Lithops are dispersed across tremendous desert territories in Namibia and South Africa. They can be found circumscribing Botswana and Angola, in regions where there isn't a great deal of water. A couple of these plants depend on dew development for dampness, since temperatures in these regions are sweltering in the mid year, and cool to cold in the colder time of year.
