C Correct answer
Explanation

Dimensions contain descriptive attributes that provide context for facts in the data warehouse. They are subject-oriented (organized around business entities like customer, product, time) and non-volatile (data doesn't change once loaded). Options A and D are wrong because dimensions don't contain facts. Option B is incorrect as dimensions contain their own descriptive data, not primarily data about other dimensions.
