D Correct answer
Explanation

A unisexual flower lacks either the androecium (male whorl) or gynoecium (female whorl), not both. Androecium is the correct term for the male reproductive whorl (stamens). Pistillate refers to female flowers, gynoecium is the female part, and perianth is the protective whorl.
