Answer 1

Answer:hope it helps you mark me

Step-by-step explanation:

Question from  Class 12  Chapter Function

As there are 5 elements in set A and 6 elements in set B,

if we try to make a one -one function from A to B, one element of B is not used.

So, function will not be onto.

If we try to make an onto function, then at least one of the elements of A should have more than one mapping to set B.

In this case, it will not be a one-one function.

So, we can not create a function that is both onto and one-one with the given sets.

So, option (c) is the correct option.
