a. 120%
b. 20%
c. 17%
d. 500%

The rate of growth in GDP can be calculated using the formula:

Rate of growth = ((new GDP - old GDP) / old GDP) * 100

Applying this formula to the given data:

Rate of growth = ((12,000,000 - 10,000,000) / 10,000,000) * 100
Rate of growth = (2,000,000 / 10,000,000) * 100
Rate of growth = 0.2 * 100
Rate of growth = 20

Therefore, the rate of growth in GDP from February to March is 20%. The correct answer is option b.
