Answer:
The correct answer would be c. haploid, each containing 23 chromosomes.
Human egg and sperm cell are haploid cells each containing 23 chromosomes.
Sperm consists of 22 autosomal chromosomes and one sex chromosome; either X or Y.
The egg consists of 22 autosomal chromosomes and a single Y chromosome.
The gametes are produced with the help of meiotic division due to which the chromosomal number gets reduced to 23 (n) from 46 (2n; parent germ cell).
