Q1. The answer is b. cones.
Reproductive structures of gymnosperms are cones while reproductive structures of angiosperms are flowers. The gametophytes are found in reproductive structures which are called cones in gymnosperms.

Q2. The answer is d. ovules.
The female gametophyte of gymnosperms develops inside the ovules borne on the surface of ovuliferous scale of an ovulate cone while the female gametophyte of angiosperms develops inside the ovules located inside the gynoecium of the flower. 

Q3. The answer is a. pollen grains.
Nevermind if a gymnosperm or an angiosperm, pollen grains are always haploid structures so when they fuse with haploid female gamete, a diploid zygote is formed.
