Solution

The correct option is B
$\begin{matrix} M a r k s o b t a i n e d & F r e q u e n c y 04 & 2 05 & 2 06 & 4 07 & 5 08 & 4 09 & 2 10 & 1 \end{matrix}$

A frequency is the number of times a data value occurs in a data set. On observing the given data, we get the frequency table as follows:

$\begin{matrix} M a r k s o b t a i n e d & F r e q u e n c y 04 & 2 05 & 2 06 & 4 07 & 5 08 & 4 09 & 2 10 & 1 \end{matrix}$
