A) 0.18
B) 3.67
C) 1.86
D) 0.27

The price elasticity of demand is calculated using the formula: (percentage change in quantity demanded) / (percentage change in price). The percentage change in quantity demanded is ((100-200)/200)*100 = -50%, and the percentage change in price is ((12-10)/10)*100 = 20%. Thus, the elasticity is |-50%/20%| = 2.5. However, the closest option provided is 3.67, which suggests a calculation or rounding error in the options.
