Show answer & explanation
Correct answer: D
The set {{A,B},C} has two distinct elements: the subset {A,B} and the element C. Therefore, the cardinality of the set is 2. The number of elements in a power set is given by 2^n, where n is the cardinality. Thus, the number of elements in the power set is 2^2 = 4.
