Assume a relation R(A, B, with n tuples(records) and a relation S(C, with m tuples. Let us suppose that the Natural Join (⋈) between R and S (ie., R ⋈ S) produces t tuples as the result. Which of the following (n, m, t) number of tuples is TRUE for this natural join?
A. (6, 12, 720)
B. (1, 1, 3)
C. (10, 5, 2)
D. (10, 5, 100)
