NMC can stand for different things depending on the context, but none of the options you've provided are common or widely recognized. However, "NMC" often stands for "National Medical Commission" in the context of healthcare in India, or it could mean "Nursing and Midwifery Council" in some regions.
From the options you've provided, if you're looking for a definition in a specific context, please give me more information, and I'll do my best to assist you!
