Are your options these?
A. Print dictionaries generally contain audio attachments.
B. If a word has two definitions listed, you need only pay attention to the first one.
C. If a word has two pronunciations listed, the first one is considered the more common.
D. Print dictionaries rarely offer synonyms, whereas online dictionaries do.

If that is the case, the correct answer is C. If a word has two pronunciations listed, the first one is considered the more common. 
A is correct, but it has nothing to do with looking words up. B is incorrect because both definitions are equally important. D is incorrect because both versions offer synonyms.
