Final Answer :
D
Explanation :
When sexual selection is strong for one sex and weak for the other, members of the sex subject to strong sexual selection will evolve traits that make them more competitive for mating opportunities, such as showy displays or physical weaponry. On the other hand, members of the sex subject to weak sexual selection will be choosier in their mate preferences due to a higher availability of potential partners, allowing them to be more selective in their investment. Therefore, choice D is the best answer as it describes members of the stronger-sex as competitive and members of the weaker-sex as choosy.
