Solution

The correct option is A 46 chromosomes
Zygote or the fertilized egg cell results from the union of a female gamete (Egg or ovum) with a male gamete (sperm). The number of chromosomes in the gamete is haploid and human gametes contain 23 chromosomes. As zygote is from the fusion of two gametes, the chromosome number is diploid and is double of that in gamete and thus has 46 chromosomes.
