Aship's foghorn will probably have a high pitch low amplitude low pitch

low pitch

Explanation:

A ship's foghorn will probably have a low pitch.

A ship’s foghorn is a very loud low-pitched horn that produces a loud noise to warn sailors and ship captains of navigational hazards such as headlands, rock outcrops, shoals or other dangers when it is very foggy. Foghorns are also used in light houses. Gongs or bells that had to be struck manually were initially used as audible fog signals before they were later replaced by foghorns.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

the correct answer is d
