From the plots, we can create a table with all the data as follows:

Profit per employee of an year = $\frac{Profit\ in \ that\ year}{Average \ of\ (Employee\ strength \ in \ that\ year\ and\ the\ next\ year)}$ .

A’s Profit per employee in 2020 = $\frac{25}{(140+150)/2}$ = $\frac{25}{145}$ = 0.17

B’s Profit per employee in 2020 = $\frac{50}{(240+250)/2}$ = $\frac{50}{245}$ = 0.20

C’s Profit per employee in 2020 = $\frac{10}{(320+320)/2}$ = $\frac{10}{320}$ = 0.03

D’s Profit per employee in 2020 = will be negative, as it had loss of 30.

Among all the profits per employee in 2020, Company B had the highest. Therefore, answer is option(a): Company B.
