Solution

The correct option is B Due to fertilization of the haploid gametes and formation of diploid zygote from which offspring develops
Meiosis is the process of cell division which reduces the chromosome number by half and this occurs in all sexually reproducing eukaryotes. So, meiosis produces haploid gametes. In sexual reproduction, when two gametes (one from male and one from female) fuses during fertilization, the result is the formation of zygote, which is diploid.
Thus, the correct answer is option B.
