A supply curve which is vertical has an elasticity co-efficient of
Answer Details
A vertical supply curve represents a situation where the quantity supplied does not respond to changes in price. This means that the quantity supplied remains constant regardless of changes in price. The elasticity coefficient is a measure of how responsive the quantity supplied or demanded is to changes in price. In the case of a vertical supply curve, the elasticity coefficient is zero because there is no change in quantity supplied even when there is a change in price. Therefore, the correct option is 0.0.
