The wording of the question is very weird, but I think the answer is (b). That is the main advantage of sexual reproduction over asexual reproduction ... it produces a *lot* more new combinations.
I don't think it's (a) because asexual reproduction will also produce offspring.
It's definitely not (c) because sexual reproduction does not reduce genetic variability, but rather *increases* it.
And it's not (d) because sexual reproduction is not "essential" for evolution ... asexual reproduction can also produce evolution.
The wording of the question is awful (are you sure you copied it exactly as written in your homework?)
Why do organisms "utilize" sexual reproduction? (Doesn't anybody say "use" anymore?) Well, they don't have any purpose in mind when they engage in sex. How is it useful to organisms? Well, yes, it makes offspring, but that's a given with the word "reproduction". The key is "sexual reproduction", and that is where (b) applies more than it does to asexual reproduction.

a-organisms only know to reproduce so that offspring will be produced.
