All of the statements are true. Intrasexual selection involves competition within a sex for mates, while intersexual selection involves attraction between sexes. Male advertisement displays, such as calling or showing off colorful feathers, are used to attract females in intersexual selection. In intrasexual selection, larger and more dominant males are likely to win fights and thus gain access to mates or resources, as seen in species such as elk or elephant seals. The antlers of male moose are indeed the result of intrasexual selection, as they are used in fights between males over mates. The bright and elaborate feathers of birds of paradise are a classic example of intersexual selection, as females choose males based on their physical traits or displays.
