Discussion

Explanation:

Even though the question asks for CAGR, we only need to compare percentage growth since the time period is the same for all regions.

Eastern Europe:

$\frac{227650-152764}{152764}$ = $\frac{74886}{152764}$ ≈ 50%

Central & South America:

$\frac{54728-42319}{42319}$ = $\frac{12409}{42319}$ < 50%

West Asia:

$\frac{235317-171661}{171661}$ = $\frac{63656}{171661}$ < 50%

South East Asia:

$\frac{409043-303475}{303475}$ = $\frac{105568}{303475}$ < 50%

Thus Eastern Europe has the highest CAGR.

Hence, option (a).
