Carpel's role in female flower reproduction

Steps:

• Identify carpel as the female organ (stigma, style, ovary) for receiving pollen and seed development.
• Link pollination to stigma, where pollen lands.
• Connect fertilization to ovary, forming seeds.
• Associate fruit formation with ovary enlargement post-fertilization.

Why C is correct:

• The carpel's stigma enables pollination, and its ovary forms fruit, per the definition of carpel as the megasporophyll enclosing ovules.

Why the others are wrong:

• A: Attracting insects involves colorful petals or sepals, not carpel parts.
• B: Producing pollen occurs in the anther of the stamen, the male organ.
• D: Releasing pollen happens via the anther, not the carpel.

Final answer: C
