This conversion is known as fusion. Within the Sun's core, fusion produces the most appreciable amount of heat energy."

Answer: The correct answer is -
B) haploid.
Meiosis is a type of cell division that occurs during the process of formation of gametes particularly sexually reproducing organisms.
Gametes are reproductive, sex cells that are haploid (having half the number of chromosomes as their parent cell).
Thus, during meiosis a diploid parent cell gives 4 haploid daughter cells, called gametes (such as eggs and sperms).
