The answer is B because he did nothin in regards to research on the stock. He also did not see if that stock was suitable for his clients accounts.

A is not the right answer because we do not know if that "huge trade" was already made or not...the question does not say.

C is not correct because this information would not count as material, non public inforrmation. If the trade has already been made, then it would be in public records.

I am making a lot of assumptions here, but to pick one right answer that would have to be what you would need to do.
