Solution
The correct option is D Assertion is incorrect but Reason is correct.
Antherozoids are biflagellate in nature. They are produced by the male sex organ called antheridium.
These antherozoids should fuse with the egg present in the archegonia that releases malic acid in water. The anthrozoids swim towards the archegonia with the help of two flagella. This is chemotatic movement in response to external chemical stimulus (paratonic)
So, the correct answer is 'Assertion is incorrect but Reason is correct.'
