How many autosomes are there in a human sperm?
A
1
B
22
C
23
D
46
Explanation: 

Detailed explanation-1: -Sperm has either 22+X or 22+Y and ovum has 22+X. Hence, there are 22 autosomes in a human gamete.

Detailed explanation-2: -Human sperm (and eggs) are in the haploid state, meaning that only have one copy of each chromosome, or 22 autosomes and one sex chromosome (either X or Y).

Detailed explanation-4: -Autosomes are the 22 pairs of human chromosomes other than the sex chromosomes. After meiosis, a sperm cell will contain 22 autosomes and one sex chromosome.

Detailed explanation-5: -In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number. In humans, n = 23.
