Hint: In this question, we will proceed by defining the term fraction and its form. Then we will define what is a unit fraction and we conclude the final answer from this definition of the unit fraction.

Complete step-by-step answer:
In mathematics, a fraction represents a part of a whole or, more generally, a number of equal parts. A fraction is of the form \[\dfrac{p}{q}\] where \[q \ne 0\].
Unit fraction: A unit fraction is a rational number written as a fraction where the numerator is one and the denominator is a positive integer. A unit fraction is therefore representing the reciprocal of a positive integer. Examples are \[\dfrac{1}{1},\dfrac{1}{2},\dfrac{1}{3}\] etc.
Therefore, from the definition the numerator of a unit fraction is one.
Thus, the correct option is B. 1

Note: A fraction has two parts. They are numerator and denominator. Numerator is the value of the above part of the fraction whereas the denominator is the value of the lower part of the fraction. For example, in a fraction \[\dfrac{3}{5}\] the numerator is 3 and the denominator is 5.
