Verified by Experts

The correct Answer is:
d
Fertilisation can not take place in absence of surface water in Fucus, Funaria and Marsilea. In these organisms fertilisation occurs oputside the body of female. A large number of gametes are released in the surrounding medium (e.g., water) where fertilisation takes place. Water is essential, so that male gametes can swim in water i order to reach female gamete. This type of fertilisation is called external fertilisation.
