By the late 1940s, ENIAC, the first electronic digital computer was able to compute a ballistics trajectory in about 30 seconds, and it was much less time than the 20 hours required to perform the same calculations with a desk calculator.

I believe the correct answer is C
A. computer was able to compute a ballistics trajectory in about 30 seconds, and it was
--> This clause should serve as a modifier, but here contains the action.
--> "and" should not be used. We're adding to the previous clause
--> "it" refers to what?
B. computer, which was able to compute a ballistics trajectory in about 30 seconds, was
--> "which" is not needed
--> "was" has a wrong subject
C. computer, was able to compute ballistics trajectory in about 30 seconds,
--> correct IMO
D. computer was able to compute a ballistics trajectory in about 30 seconds, being
--> Same as A)1
--> "Being" is wrong.
E. computer, and was to compute ballistics trajectory in about 30 seconds, and was
--> "and was" is wrong, because we haven't finished a clause yet.
--> second "and was" wrong also for above-cited reasons.
