Explanation:

In magnetism, the fundamental principle that like poles repel and opposite poles attract is known as the "law of magnetism". The term "law" is used in scientific contexts to denote a well - established and fundamental principle. Options A ("rule of magnetic theory") and D ("rule of magnetism") use the term "rule" which is less formal and less commonly used in the scientific naming of this principle. Option B ("magnetic rule") is too vague.

Answer:

C. "law of magnetism"
