I would go with E. Whats the OA??

B. Columbus was the Incan highway, over 2,500 miles in length, and extended - The usage of , before over does not make sense
C. Columbus, the Incan highway, which was over 2,500 miles in length and extended - this would have been right if 'which' is taken out
D. Columbus, the Incan highway, being over 2,500 miles in length, was extended - unnecessary use of the word being.
E. Columbus, the Incan Highway was over 2,500 miles long, extending - Modified correctly placed. Extending participle is correctly used. I would go with E.

same reason as above for abc, i narrowed it down to d or e.
i found that d changed the meaning of the sentence but seemed grammatically okay. d seems to say that the highway was extended due to the fact that it was 2500 miles long.

so i went with e.

Hi sdrandom1,

Hi tkarthi4u,

C is missing the main verb that is necessary to make this sentence a complete sentense. It is missing the word 'was'. C would have been right if it said -

C.Columbus was the Incan highway, which was over 2,500 miles in length and extended
but instead the option given to us is -
C. Columbus, the Incan highway, which was over 2,500 miles in length and extended

Make sense???

BTW Sudeep, the link that you sent as duplicate does not lead to this same question.
