The nucleus is present in which part of the mammalian male sperm?

Head

The correct answer is Option (1) - Head

The nucleus of the mammalian male sperm is located in the "Head" region.

The head contains the genetic material (chromosomes) necessary for fertilization. The head is also covered by a cap-like structure called the acrosome, which contains enzymes that aid in the penetration of the egg during fertilization. The tail, middle piece, and neck are other structural components of the sperm cell involved in motility and energy production.
