In angiosperms, pollen grains are

Adiploid and are made when haploid gametes join in fertilization
Bdiploid and are made when haploid gametophytes join in pollination
Chaploid and are made when haploid spores undergo mitosis
Dhaploid and are made when haploid ovules undergo meiosis. i think it's b but i feel like i'm way off :(

Verified Answer :

CHapliod, and are made when haploid spores undergo mitosis

Answer:

The correct answer would be c. haploid and are made when haploid spores undergo mitosis.

Angiosperms are flowering plants.

Pollen is formed in the anther of the flowering plant. Pollen is haploid in nature as they are formed from the meiotic division of microspore mother cell. This process is termed as microsporogenesis.

Later, these microspores develop into the microgametes by the process termed as microgametogenesis. Under this process, the microspore undergoes mitotic division and produce two haploid nuclei. One nucleus is termed as the vegetative nucleus and another is termed as the generative cell.
