Step-by-step explanation:
The NCO Subcommittee was responsible for advising on enlisted matters, option C). As part of this role, they played a significant part in shaping the policies and procedures affecting non-commissioned officers (NCOs) within the military. This would involve matters such as pay, promotions, training, and benefits, ensuring that the interests and welfare of enlisted personnel are considered.
