Correct option is
B

Given that

The electron is freely in a closed cubic box (CCB) of length

Also given that

The electron is freely moving inside the box.

Therefore,

The maximum uncertainly in position will be equal to the length of the diagonal.

So,

Β 

Β Hence,

The maximum uncertainty in its velocity
