B Correct answer
Explanation

In composite (Asteraceae) flower heads, florets can be of two types: ray florets (strap-shaped, often sterile) and disc florets (tubular, usually bisexual). When both types are present, the head is called heterogamous. Homogamous heads have only one type of floret. Monoecious and polygamous refer to sexual types, not floret diversity.
