Answer:

d is correct ✅ answer......

Answer 2

Answer:

Option (C) Half sperm during spermatogenesis

Explanation:

• The German biologist Henking first discovered the X- chromosome (X for unknown) in certain insects. During his research studies, he found traces of nuclear structures all through the process of spermatogenesis, which he named - X body or unknown body.

• He also observed that exact half of the sperms carried this X body while the remaining half did not.

Thus option (C) is correct.

• Later scientists revealed that this unknown X body observed by Henking was a chromosome, thus named it the X chromosome.

Hence option C is correct.
