Answer and explanation
Correct answer: {1/2}
R denotes the set of real numbers, while Z denotes the set of integers. The number 1/2 is real, so every element of {1/2} belongs to R. However, 1/2 is not an integer, so this set is not a subset of Z. The other listed sets contain only integers and are subsets of both R and Z.
