any disease may include malaria itself. so we have to exclude malaria. therefor use of 'other' is necessary here.
D is out due to wrong idiom more than as


C grammatically correct but other is missing
A and B out similar reasons. also use of which is not correct

[StaceyKoprince]

In C, the word "does" refers back to the verb "ravages," so what that option would be saying is:
"Malaria ravages more people than (it) ravages any disease"
That doesn't make sense - the meaning should be that malaria ravages more people than any other disease ravages people. It doesn't make sense to say that malaria ravages other diseases.

That logic allows us to get rid of A and B in addition to C, by the way. (A and B are basically saying the same thing.)
