Final answer:

The sensory organ of the SCC is the crista ampullaris, which detects rotational head movements for balance, not to be confused with the macula or the organ of Corti, which are involved in detecting linear movements and the sense of hearing, respectively.

Step-by-step explanation:

The sensory organ of the semicircular canals (SCC) is the crista ampullaris. Unlike the macula which is found in the utricle and saccule within the vestibule and detects linear movements, the crista ampullaris is responsible for detecting rotational movements of the head that contribute to our sense of balance.

Different from the organ of Corti which is located in the cochlea and is crucial for audition -- the sense of hearing -- by transducing movements from sound waves into electrochemical signals.

Final answer:

The sensory organ of the SCC is the crista ampullaris, which detects rotational movements of the head. B is the correct answer.

Step-by-step explanation:

The sensory organ of the semicircular canals (SCC) is the crista ampullaris, which is responsible for detecting rotational movements of the head that aid in our sense of balance and spatial orientation.

The other options given were a. macula, which is found in the utricle and saccule and detects linear acceleration, and c. the organ of Corti, which is located in the cochlea of the inner ear and is responsible for transducing sound waves into electrical signals that the brain can interpret as hearing.

The mentioned correct option in the final answer concerning the SCC is the crista ampullaris.
