Hi!<br/><br/>I read the following question in a TOEIC book:<br/><br/><br/><br/>"9. As the new chairman did not approve <i>______</i>, we had to come up with a new solution.<br/><br/><br/><br/>(A) the idea<br/><br/>(B) on the idea<br/><br/>(C) of the idea<br/><br/>(D) about the idea<br/><br/><br/><br/>(Answer: C)”<br/><br/><br/><br/>Do you agree with the above that C is ONLY correct?<br/><br/>What about A?<br/><br/>Don’t you say “the chairman did not approve the idea”?<br/><br/><br/><br/>Thanks in advance.
