Answer: Option C
Answer: (c)The most suitable phrase to fill the blank is ‘get back to’ which means to return to someone or something. This phrase is often used to say that you will return with an answer to a question or a request at a later time. All the other phrases fail to provide the appropriate context to the sentence. Hence, option (c) becomes the most viable answer choice. get up means (of wind or the sea) become strong or agitated. get back at means take revenge on (someone). get along with means another way of saying get on. get around means deal successfully with (a problem).
