The correct answer is Option (2) → Parthenocarpic fruit

Option (1) True fruit — Incorrect. A true fruit develops from the ovary after fertilisation.

Option (2) Parthenocarpic fruit — Correct. A fruit that develops without fertilisation is a parthenocarpic fruit. It has no seeds; banana is an example, and such fruits can also be produced by applying growth hormones.

Option (3) False fruit — Incorrect. A false fruit develops from the thalamus as well as the ovary, as in apple.

Option (4) Polyembryonic fruit — Incorrect. Polyembryony is the presence of more than one embryo in a seed.

NCERT Extract:
Seed – “… In most plants, by the time the fruit develops from the ovary, other floral parts degenerate and fall off. However, in a few species such as apple, strawberry, cashew, etc., the thalamus also contributes to fruit formation. Such fruits are called false fruits (Figure 1.15b). Most fruits however develop only from the ovary and are called true fruits. Although in most of the species, fruits are the results of fertilisation, there are a few species in which fruits develop without fertilisation. Such fruits are called parthenocarpic fruits. Banana is one such example. Parthenocarpy can be induced through the application of growth hormones and such fruits are seedless.”
