The answer would be: C) sexual selection.
Sexual selection happens where one of the individuals choose the partner to sex based on some criteria. In this case, the ability to have a beautiful bower will determinate the ability of the bird to have sex and produce offspring. The criteria are not limited to visual. It could be diverse in other cases, like a deeper croak in frog

Answer:
Why are molecules such as valinomycin effective at transporting ions across the membrane?
Valinomycin is effective as transporting ions across the membrane because it is no charged, so it can carry ions.
Why would a drop in temperature to or below the transition temperature limit valinomycin mediated K+ transport across the plasma membrane?
Valinomycin is limited by temperature because its activity is highly sensitive and it depends on a stable and an average temperature.
Explanation:
Valinomycin is effective at transporting ion across the membrane because is an antibiotic that alternates hydroxy and amino acid, ans it helps membranes to be permeable. Valinomycin is a cyclic molecule that helps in ions transportation through membranes. Also, antibiotics have a temperature range of activity, that's why it is sensitive to changes.
The cell membrane is semi-permeable, kind of like a filter to let some molecules in and keep larger molecules out
