Answer and explanation
Correct answer: J = {S, T, A, I, C}
The word STATISTICS contains the letters S, T, A, T, I, S, T, I, C, S. In a set, each element is written only once because repetition does not create a new element. Thus the distinct letters are S, T, A, I, and C. Their order in roster form is not important, so option A correctly represents J.
