Using the midpoint method formula:

Elasticity of supply = ( % change in quantity supplied ) / ( % change in price )

% change in quantity supplied = ( 100 - 75 ) / ( ( 75 + 100 ) / 2 ) x 100% = 22.22%

% change in price = ( 20 - 18 ) / ( ( 18 + 20 ) / 2 ) x 100% = 11.11%

Elasticity of supply = 22.22% / 11.11% = 2

Since the elasticity of supply is greater than 1, it indicates that supply is elastic. Therefore, the correct answer is C.
