Answer: 4. (a) and (d)

Key idea: Two generations one inside the other means a gametophyte developing inside a sporophyte structure, i.e., a haploid stage retained within a diploid one.

(a) The pollen grain (male gametophyte) lies inside the anther (sporophyte). (d) The embryo sac (female gametophyte) lies inside the ovule (sporophyte). In (b) a germinated pollen grain is only the gametophyte, and in (c) a seed inside the fruit is wholly sporophytic. So (a) and (d).
