Verified by Experts

The correct Answer is:
A
The production of offspring by sexual reproduction includes the fusion of two gametes, each with complete haploid set of chormosomes, For this, gametes are formed from specialised diploid cells which undergo meiosis that reduces the chromosome number by half resulting in the production of haploid daughter cells.
