Assertion (A) : Parthenocarpy involves formation of seedless fruit.
Reason (R) : Apomixis occurs without fertilization.

The correct option is B Both assertion and reason are true but reason is not the correct explanation of assertion
Parthenocarpy (virgin fruit) is the natural or artificially induced production of fruit without fertilisation of ovules, therefore the fruit is seedless.

Apomixis is a form of asexual reproduction, seen in plants, where the development of an embryo or the seed occurs without fertilization.
