The correct answer is A. Rohit is a very courageous boy.
A courageous person is not afraid to do things that are dangerous or difficult. They are willing to face their fears and take risks in order to achieve their goals. Rohit is a courageous boy because he is not afraid to stand up for what he believes in, even when it is difficult. He is also willing to help others, even if it means putting himself in danger.
B. Naughty is not the correct answer because it means “disobedient or mischievous.” Rohit is not a naughty boy; he is a courageous boy.
C. Cowardly is not the correct answer because it means “lacking courage.” Rohit is not a cowardly boy; he is a courageous boy.
D. Happy is not the correct answer because it means “feeling or showing pleasure or contentment.” Rohit may be happy, but that is not the reason why he is a courageous boy.
