Solution:
Numeric data stored in because numeric variables fall into the following two main categories:
Integer variables hold values that have no fractional part (that is, whole numbers only). Integer variables come in two flavors: signed integer variables can hold positive or negative values, whereas unsigned integer variables can hold only positive values (and 0).
Floating-point variables hold values that have a fractional part (that is, real numbers).
Thus the right answer is B.
