Explanation Reason for the correct statement: Phrenic nerve is one of the most important and major nerve which originates from the neck and passes between the heart and lung reaches the diaphragm. Option (c) is given as “phrenic nerve”. As “the major nerve of the cervical plexus that innervates the diaphragm is the “phrenic nerve”, it is the right answer. Hence, option (c) is correct. Reasons for the incorrect statements: Option (a) is given as “median nerve” It is the only nerve that passes through the carpel tunnel and controls the muscles of forearm...
