Question

Which shows the best use of parentheses?

Answer 1

Answer:

It's C

Explanation:

When did Magic Johnson first lead his professional team to a world championship: (a) 1980, (b) 1981, or (c) 1982?

Answer 2

The correct answer is C.  
A does not make sense as it "blocks" the whole section of choices. 
B does not make sense either, it is trying to place parenthesis where no emphasis whatsoever needs to be given.  
D is wrong because of the same things that are wrong with B.
C is correct because it correctly separates the letter choices from the answers, giving information with the correct context.
