Solution

The correct option is A
A B
Gametophytic generation (n) Sporophytic generation (2n)

A - Gametophytic generation (n)
B - Sporophytic generation (2n)

In angisperms, the gametophytes are haploid (n) structures such as the pollen grain and the egg cell that act as gametes and fertilise to form a zygote which marks the beginning of the sporophytic generation. Sporophytes are diploid (2n), i.e., they have two sets of chromosomes and form the dominant plant body.
