Solution

The correct option is B
The intervals should be divided as follows:
$\begin{matrix} 1^{s t} c l a s s i n t e r v a l & 40 - 45 2^{s t} c l a s s i n t e r v a l & 45 - 50 3^{r d} c l a s s i n t e r v a l & 50 - 55 4^{t h} c l a s s i n t e r v a l & 55 - 60 5^{t h} c l a s s i n t e r v a l & 60 - 65 \end{matrix}$
Therefore, the first class interval should be $40 - 45$ .
