Given range of set A is 5
Given range of set B is 11

Range of \(A\cup\ B\) is always greater than or equal to the range of the set with greater range.

So, Range(\(A\cup\ B\))\(\geq{Range(B)\).
Or, Range(\(A\cup\ B\))\(\geq{11}\).

Ans. (A)

What if 0 is an element of one of the sets? Then 10 is also possible

=>

For example, if A = {0,5} and B = { 0, 11 }, then the set A is included in the set B and the smallest possible range of the sets A and B combined is 11, which is the range of the set B.
Thus, any number less than 11 cannot be the range of sets A and B, combined.

Therefore, A is the answer.
Answer: A
