Solution

The correct option is B If both Assertion and Reason are correct, but Reason is not the correct explanation for Assertion
Antherozoids of Funaria move toward the archegonium in response to the sugars secreted by the latter. This is an example of chemotropic movement, which is motion in response to an external chemical stimulus. This is also known as paratonic movement as it occurs in response to an external stimulus, that is, chemicals secreted from the archegonium. Thus, both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
