Final answer:
The result of human male preference in mate selection is that women will compete for a man's attention. This competition arises from sexual selection, where intersexual competition sees individuals of one sex competing to be chosen by the other sex, as observed in various species, including humans.
Step-by-step explanation:
The question inquires about the results of human male preferences in mate selection and the subsequent behaviors in females. In the context of sexual selection, which is a specific case of natural selection identified by Charles Darwin, the preferable traits in mating partners can lead to various behaviors in the chosen gender. Male preferences can lead to intrasexual competition, where members of the same sex compete for the attention of potential mates. Hence, the answer to the question is that women will compete for a man's attention (option c). This competition manifests in various species, with specific strategies employed based on their ecological and social contexts. For example, male bowerbirds build elaborate nests to attract females, while male peacocks display vibrant plumage to catch the eye of potential mates, a process known as intersexual selection.
In a more human context, while male preferences might also lead indirectly to competition in other social spaces, such as the workplace, the question is specifically addressing mate selection. Therefore, the most directly related result of male mating preferences is that women may compete for male attention, engaging in their own sets of behaviors that are attractive to potential mates. This intersexual competition is a widespread phenomenon observed across a multitude of species, including humans.
