Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
In some species of Asteraceae and Poaceae, seeds are formed without fertilisation. This is due to the direct development of a seed into an embryo without any meiosis. Production of seeds without meiosis and fertilisation is called apomixis.
Whereas the development of fruit without fertilization is called parthenocarpy.
Hence, both the assertion and reason are correct but the reason is not the correct explanation of assertion.
So, the correct option is 'Option B'.
