the answer so C- they are passed along to offspring.
an adaptation is a genetic change overtime that makes an organism better suited to their environment. organisms with some adaptions pass on their genes more than organisms without it, making them appear more often in a population.
A is not true because they are not learned, they are naturally acquired through mutations or genetic recombinations.
B is not true because genetics cannot really be changed that much during lifetime unless there is a mutation. still, a change acquired during an organisms lifetime would not be passed down to the offspring.
D is not true because a part of an organisms genetic makeup would not disappear all of the sudden.
