Solution

The correct option is C If the assertion is true but the reason is false
The fusing gametes in the lower forms of algae are alike in size, structure and behaviour. They are indistinguishable as to sex. Such gametes are called the misogamies. Sexual reproduction which involves the fusion of misogamies is termed isogamous. It is a primitive type of sexual reproduction.
