Question
All of the following conditions support cross-pollination, except:
Correct Answer
Option C is the correct answer.
Detailed Explanation
Protandry (male parts mature first) and dioecious plants (separate male and female plants) both favor cross-pollination by preventing self-pollination. Monoecious plants have both male and female flowers on the same plant, which can allow for self-pollination, but can also lead to cross-pollination. 'Polygyny' is a mating system in animals, not a botanical term that supports or inhibits cross-pollination, making it the incorrect option in this context.
Hint
Consider which terms are botanical strategies for reproduction and which might be out of context.
