ya, option (b) definitely doesn't work.
"greater than..." can only be used to compare two kinds of things:
1/ NOUNS representing things that can be compared quantitatively;
2/ actions formed from "to be" or from similar verbs, such as "to seem ADJ", "to appear ADJ", and so on -- basically, the kind of verbs that say what someone or something is, not what he/she/it does.
so, "greater than..." can compare two amounts.
also, although this doesn't happen in the problem at hand, it can compare item #2 above: my body fat percentage is 2% greater than it was last year.
"greater than..." cannot be used to compare action verbs, such as "raised".
so, your instinct is closer to the mark than the OA here.
