Answer: Option C

Explanation:

To solve bar graph or any other type of data interpretation questions, its very important to make use of eyes too, by having a look on graph we can solve many questions quickly, sometimes it helps us get the correct answers or some times it helps us eliminate few options from given options.

So let solve now,
if you see graph, it is really visible that shampoo is the right answer.

But still lets solve for the sake of explanation.
\begin{aligned}
Lipsticks = \left[\frac{(48.17-20.15)}{20.15}* 100\right] \% \\
= 139.06 \% \\

\text{Nail Enamels} = \left[\frac{(37.76-5.93)}{5.93}* 100\right] \% \\
= 536.76\% \\

\text{Shampoos} = \left[\frac{(12.21-7.88)}{7.88}* 100\right] \% \\
= 54.95\% \\

\text{Conditioners} = \left[\frac{(10.19-5.01)}{5.01}* 100\right] \% \\
= 103.39\% \\

\end{aligned}
So Shampoo is approx 55%
