Question

Colin told me about his new job, -----------very much​
A. Which he is enjoying B. That he is enjoying C. He is enjoying D. He is enjoying it

Answer 1

Answer:

Colin told me about his new job, he is enjoying it very much.

Answer 2

Colin told me about his new job, he is enjoying it very much.

Answer: Option D  

Explanation:

The presence of the comma at the end of ‘job’ in the sentence, Colin told me about his new job, -----------very much, signifies that the sentence will be two simple sentences and not a compound or complex sentence. For a compound sentence there are two or more main clauses joined by connectors. There are no connectors in the given options.  

For a sentence to be complex there must be a linking pronoun like ‘that’ or ‘which’ but in those cases commas are not used.
