Question

A fruit which develops from a single ovary of a single flower is
A)Accessory fruit
B)Simple fruit
C)Single fruit
D)Pseudocarp

Answer 1

An aggregate fruit is a fruit that grows from the amalgamation of many ovaries divided into a single flower. In addition, from one ovary, simple fruit forms.

Complete answer:
An accessory fruit is defined as a fruit which has some flesh derived from adjacent tissues outside the carpel and not only from the ovary.
The simple fruits are the fruits found in angiosperms which develop from one ovary present in only one flower. The ovary may be either simple or compound. The true fruits are defined as the fruits which have a single component of aggregate fruit.
The pseudocarp or the false fruit is a fruit which includes along with the ovary wall different plant parts like the receptacle. e.g. fleshy part of strawberry fruit is because of receptacle and `pips' present on the surface of the fruit. These form the true fruits.

Different types of fleshy and simple fruits are:
Berry - ( tomato, avocado)
Stone fruit drupe - (plum, cherry, peach, olive)
False berry - accessory fruits (banana, cranberry)
Pome - accessory fruits (apple, pear, rosehip)

Hence, the correct answer is option (B)

Note: Drupe is considered to be a simple fleshy fruit which usually contains only one seed, like cherry, peach, and olive. A drupe is produced as a simple fruit from a single ovary of an individual flower.
