The price of a product increases by 12%, and this leads to a short-run increase in quantity supplied of 5%. What is the elasticity of supply for this product?

This value suggests that for every 1% increase in price, the quantity supplied increases by only 0.75%. Given the provided price and quantity changes, this elasticity does not accurately reflect the relationship observed in the scenario, leading to a miscalculation of the responsiveness of supply to price changes.

An elasticity of 3 would imply that a 1% increase in price results in a 3% increase in quantity supplied. This indicates an extremely high responsiveness, which does not align with the observed data of a 5% supply increase for a 12% price increase. Hence, this option overstates the actual elasticity.

This elasticity suggests that a 1% increase in price results in a 1.08% increase in quantity supplied, which indicates a relatively inelastic response. Since the actual observed data indicates a lower responsiveness, this choice does not accurately reflect the situation described in the question.
