B. that is similar to artificial vision but one that has proved easier to solve.
C. similar to that of artificial vision but it has proved easier to solve.

A. that is similar to artificial vision, but the solution has proved easier. -- problem is compared to artificial vision.Hence POE.

B. that is similar to artificial vision but one that has proved easier to solve. -- problem is compared to artificial vision.Hence POE.

C. similar to that of artificial vision but it has proved easier to solve. -- the second clause with the subject 'a problem' needs to be paralleled after using 'but'. 'It' doesn't clearly refer to ' problem'. Hence POE.

D. similar to that of artificial vision, but the solution has proved easier. -- parallelism issue after coordinating conjunction but.Hence POE.

E. similar to that of artificial vision but one that has proved easier to solve. -- 'One' clearly refers to 'problem'.Hence it is the OA.

Can someone please explain the choices between C and E? Why is choice E better than C?

Nice explanation. The use of "it" is ambiguous, while the use of "one that" clearly refers to a problem.
