Select the sentence that corrects the error in the following. because i saw the accident, i was asked to testify, and i was nervous. a. i saw the accident, i was asked to testify. and i was nervous. b. because i saw the accident. i was asked to testify. i was nervous. c. there is no error.

C. There is no error.

Explanation:

A. is incorrect because it contains a comma splice which is the use of a comma to join two independent clauses: "I saw the accident, I was asked to testify."

B. is incorrect because it contains a fragment: "Because I saw the accident" does not contain even one independent clause and cannot stand by itself as a sentence.  

C. is correct because the sentence in question is a compound-complex sentence as it contains two independent clauses and one dependent clause and uses punctuation correctly.
