Answer: C - Cedarwood oil
The clearing agent that is recommended for use on central nervous system tissues and other cytological studies is the Cedarwood oil. This is due to the fact that central nervous system tissues and other smooth muscles are very delicate and can easily be distorted. Thus, the recommended clearing agent to be used must not cause distortion of the tissue sample. All other options are not the choice for use on central nervous tissues and other cytological studies.
