As there are only $13$ possible values a variable can take, we need to use $\lceil 13 \rceil = 4-bits.$

PS: As variable can take only 13 values, we don't need to worry what those values are.

I think Option e
because what kind of value(range) its not mentioned so we cant decide the bits for the variable.
