Complete answer:
noise pollution – it's also called environmental noise or sound pollution which has harmful effects on the activity of human or animal life. The disturbance produced in our surroundings by the unwanted loud sounds of several kinds is named sound pollution. People use various electrical gadgets for their own comfort and everyone. These gadgets produce noise.
Sound pollution is one of the most polluting in various metro cities. This sort of pollution is harmful for the health of several species that have begun to regulate their vocal calls in an effort to be heard above the din. Male great tits (Parus major) for instance, are noted to vary the frequency of their call so as to be heard over anthropogenic noise.
Female great tits prefer lower frequency calls when selecting a mate, but these frequencies are harder to hear over urban noise. Males who sing at higher frequencies are less attractive to females, but females may still mate with them if there are not any lower-frequency singers available. Males are therefore placed in a difficult position—sing at a lower frequency and not be heard, or sing at a higher frequency and potentially be dismissed.

Hence the correct answer is that the (D).
