Practice question

Correct option is B, One functional gamete. In Reproductive System, the accurate description is One functional gamete, and that is what you should commit to memory. Keep the definition tight and the role clear — cause and effect line up with One functional gamete — that is the mechanism or reason the stem is pointing to. Then One functional gamete is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto One functional gamete.
