    A

    Explanation:

    in DNA there is complementary base pairing which is that Adenine always pairs with Thymine and Cytosine always pairs with Guanine. therefore, if there is a certain amount of adenine in the DNA it must have the same amount of its complementary base, thymine.

    the answer cannot be b as cytosine and thymine are not complementary base pairs. although b can coincidently be correct - that the amount of cytosine and thymine are equal - the question states that it must always be true. the answer cannot be c as ribose is found in RNA and deoxribose is found in DNA.
