Question

Which of the following arrangement cannot be possible?

• A. n = 4, l = 2
• B. n = 5, l = 5
• C. n = 3, l = 2
• D. n = 1, l = 0

Answer 1

The correct option is B

n = 5, l = 5

We know that,
'l' can have maximum value as n - 1.
Therefore, for
n = 4 $\Rightarrow$ 0 to 3
n = 5 $\Rightarrow$ 0 to 4
n = 3 $\Rightarrow$ 0 to 2
n = 1 $\Rightarrow$ 0
Therefore, option (b) is not possible.
