Solution:
Option(D) is correct

Let, the expenditure of Company $R$ in 2000 be $x$ million US $\$$

Then, expenditure of Company $R$ in 2001:

$=\left(\dfrac{120}{100}\right) ×x$ million US $\$$

$⇒ \left(\dfrac{120x}{100}\right) = 45$

$⇒ x = 37.5$

i.e., expenditure of Company $R$ in $2000 = 37.5$ million US $\$$

Let the income of Company $R$ in $2000$ be $I$ million US $\$$

Then, $10 = \left[\dfrac{I - 37.5}{37.5} × 100\right]$ [$\because$ % Profit in 2000 = 10%]

$⇒ I - 37.5 = 3.75$
$⇒ I = 41.25$

i.e., Income of Company $R$ in 2000 = 41.25 million US $\$$
