No need workings, just final answer

No need workings, just final answer Let A be a set with m elements, B be a set with n elements, and R be a relation from A to B. What is the total number of elements in the domain and range of R? Select one: O a.

Let A be a set with m elements, B be a set with n elements, and R be a relation from A to B. What is the total number of elements in the domain and range of R? Select one: O a. The total number of elements in the domain of Ris m, and the total number of elements in the range of Ris n. O b. The total number of elements in the domain of Ris m, and the total number of elements in the range of R is less than or equal to n. oc The total number of elements in the domain of R is less than or equal to m and the total number of elements in the range of R is less than or equal to n. O d. 1 The total number of elements in the domain of R is less than m, and the total number of elements in the range of Ris n. Let A = {a, b, c, d}, B = {1, 2, 3, 4, 5). What is the number of elements in a relation from A to B? Select one: a. 4 O b. 9 Oc. Less than or equal to 20 O d. 20 Is the set of all rational numbers in (-100, 200) under usual order s well-ordered? Why? Select one: O a. No, as it does not have the greatest element O b. No, as it does not have both the least and greatest elements. Oc. No, as it does not have the least element d. Yes, as it has the least element - 100 and greatest element 200 The following is a proof for n+1
