# Mark the correct alternative in the following:

Let A = {1, 2, 3}, B = {2, 3, 4}, then which of the following is a function from A to B?

A.{(1, 2), (1, 3), (2, 3), (3, 3)}

B. {(1, 3), (2, 4)}

C. {(1, 3), (2, 2), (3, 3)}

D. {(1, 2), (2, 3), (3, 2), (3, 4)

Answer :

A function is said to be defined from A to B if each element in set A has an unique image in set B. Not all the elements in set B are the images of any element of set A.

Therefore, option C is correct.
