Yes it should be C

In a series of two or more elements, what u put on #2 determines on the remaining elements..
Ex:I like to swim,to run and to dance.
I like to swim,run and dance

are correct.

Yes. Between A & C, A has can, which is a modal verb that changes the certainty of the stem. This is against what GMAT rules, so C is correct.

'can' in A and B is redundant
D,E -> awkward sentences.

C is best.
