Throughout the evolution of the land plants, the sporophyte generation has become and more independent of the gametophyte, and the gametophyte generation has become and more dependent on the sporophyte.

a. larger; smaller
b. larger; larger
c. larger or smaller; larger
d. smaller; smaller
e. smaller; larger

A. larger; smaller

Explanation:

The life cycle of plants is divided into two phases that is the sporophyte and the gametophyte.

In non-vascular plants, the gametophyte generation remains dominant and larger in size compared to the sporophyte but during the evolution of the plants from the non-vascular to vascular plants the gametophyte generation size has reduced while the sporophyte generation has become very large compared to the gametophyte.

Thus, Option-A is the correct answer.
