If A = {0, {0}}, which of the following is an element of P(A)?
Answer and explanation
Correct answer: {0}
The power set P(A) consists of all subsets of A. The set A has two elements: the number 0 and the set {0}. The set {0} contains only the element 0, which belongs to A, so {0} is a subset of A and therefore an element of P(A). In contrast, 0 is an element of A but is not itself a subset of A.
