A is out because we are only given percentages and we do not about the total dollar sales. percentage can be the same and the actual amounts may vary.

B We cannot say this based on the given data

C hold on to it

D Same as B

E reads more than what is given

Lets say the total sales is 1000 and the total profit is 100

PH has sold stuff worth 200$ and made 40 dollars profit

CH has sold stuff worth 800$ of it and made 60 dollars profit

So we can say that the chemical division has lesser profit per dollar sales compared to PH?

OA is C.
I get it now. Thank you for your explanation.
