If `A={x,y,z}" and "B={a,b,c,d}`. Then, which one of the following is not a relation from A to B ?

A

`{(x,a),(x,c)}`

B

`{(y,c),(y,d)}`

C

`{(z,a),(z,d)}`

D

`{(z,b),(y,b),(a,d)}`

Text Solution

Verified by Experts

The correct Answer is:
D

`{(z,b),(y,b),(a,d)}` is not a relation from A to B because `a !in A`.
