Final answer:
A perfect flower contains both male and female reproductive parts, which include stamens (androecium) and carpels (gynoecium); thus, the answer is e. carpels and stamens.
Step-by-step explanation:
A perfect flower contains both male and female reproductive structures, which means it includes stamens and carpels. The stamens, or androecium, contain the anthers where pollen grains develop. The carpels, or gynoecium, consist of the stigma, style, and ovary. Since perfect flowers contain both these structures, the correct answer is petals, stamens, and carpels. Therefore, a perfect flower contains: e. carpels and stamens.
