• A. The middle piece of sperm
• B. Polar bodies
• C. Acrosome
• D. Mature eggs

Answer 1

The correct option is D

Mature eggs

The correct option is D.

Explanation for correct option:

1. Fertilizing is a sperm-agglutinating agent developed by an egg that aids in the preliminary stages of fertilization.

2. They offer energy for the sperm to travel around.

Option B:

1. Polar bodies are cells that form when an oocyte separates during meiosis.
2. It contains a nucleus produced during the first or second meiotic division.

Option C:

1. The acrosome is a distinct membranous organelle found over the anterior part of the sperm nucleus that has remained largely unchanged throughout evolution.
2. This acidic vacuole contains a number of hydrolytic enzymes that, aid sperm penetration through the egg coats when secreted,

Final answer: Fertilizin is a chemical substance that is produced from mature eggs.
