Solution

The correct option is B Chemotaxis
Movement of sperms towards archegonial necks due to component of their exudate is because of chemotaxis. Chemotaxis is movement of an organism in response to a chemical stimulus. Somatic cells, bacteria and other single cell or multicellular organisms direct their movements according to certain chemicals in their environment.
