Question:

Assertion: When the supply curve is vertical, the elasticity of supply is undefined.

Reasoning: When the supply curve is vertical, supply is completely insensitive to price.

Options:

Both Assertion (A) and reasoning (R) are correct and but R is not the correct explanation of A.

Assertion (A) is true but Reasoning (R) is not correct.

Assertion (A) is not true but Reasoning (R) is correct.

Correct Answer:

Assertion (A) is not true but Reasoning (R) is correct.

Explanation:

The correct answer is Option 4: Assertion (A) is not true but Reasoning (R) is correct.

Assertion:When the supply curve is vertical, the elasticity of supply is undefined.This assertion is incorrect. When the supply curve is vertical, the elasticity of supply is zero, not undefined.

Reasoning: When the supply curve is vertical, supply is completely insensitive to price. This reasoning is correct. A vertical supply curve means that the quantity supplied remains constant regardless of changes in price. This indicates perfectly inelastic supply.
