Then, Q={1, 1/2, 1/3, 1/4, 1/5, .....}

Step-by-step explanation:

We know,

N = {1, 2, 3, 4, 5, .....}

Then,

Q={1, 1/2, 1/3, 1/4, 1/5, .....}

Q will be an infinite set.

I think this is the answer

As per question y belongs to natural no. set

So if you put any natural no. except 1 you get answers in fraction like 1/2, 1/3,...

By putting y=1, you get option b

As we know,

N = {1, 2, 3, 4, 5, .....}

Then,

Q={1, 1/2, 1/3, 1/4, 1/5, .....}

thus b is correct answer

N = {1, 2, 3, 4, 5, .....}

Then,

Q={1, 1/2, 1/3, 1/4, 1/5, .....}

thus b is correct answer
