The correct answer is Hamlet reacts with his heart and does not clearly think through situations.
He is deeply emotional character. He claims to carry out revenge on his father`s death in the Act I, but he suffers to do so for many weeks, even month. So, it shows that he lives by his heart and doesn`t think through all the situation.
Also, he suffers to express his love for Ophelia as he is too emerged with revenge of his father`s death.
