I NEED THIS ANSWER ACAP! This story is "Mysterious Olm!!!"

One of the central ideas of the "Mysterious Olm" is that the olm has adapted well to its environment. Which evidence from the text BEST supports that idea?

a: "The adult olm grows to a length of about 30 centimeters, or about 12 inches, and the female is somewhat larger than the male. The olm's body is long and slender with a flat tail."

b: "Unlike most creatures (including its owns cousins), the olm can live more thank 100 years. Scientists have yet to discover why."

c: "But the olm doesn't need its eyes to locate its prey. Instead, it relies on its super keen senses of smell and hearing."

d: "In one cave in France, a laboratory has been designed to resemble the olm's natural habitat."
