Solution
The correct option is A 4
Haploid refers to a cell containing a single set of chromosomes.
Human beings are diploid organisms, i.e., most of the cells in their bodies(except gametes) possess two sets of chromosomes (2n).
In the structures given above,
Secondary spermatocyte- Haploid
Oogonia- Diploid
Spermatid- Haploid
Spermatogonia- Diploid
Primary Oocyte- Diploid
Spermatozoa- Haploid
Polar body- Haploid
4 are haploid.
