• C. 450

Answer 1

The correct option is A 45

Pollution caused by fossil fuel = 0.45 parts of the total pollution.

To convert it to percentage, first write it in fraction form.

0.45 = $\frac{45}{100}$

To convert it into percentage, multiply by 100 %.

$\frac{45}{100}$ $\times$ 100% = 45 %

Hence, pollution caused by fossil fuel is 45%.
