A
ability + have is incorrect
like is incorrectly used

ability in is incorrect
able to is correct

has is needed

you can solve it using meaning also

ABE are simply out

D says
scientist have become ever more accurate
and C says
Scientists provide mroe accurate models

so C is better

The ability of scientists has not become accurate. The models have become accurate as scientist are now more able.
Can rule out A, B, D and E. We can also rule out 'D' for using ability for.
C it is.
Correct me if I am wrong.
