Correct option is B
The correct answer is (B)
An isoquant represents all the combinations of two inputs (typically labor and capital) that produce the same level of output.
Explanation:
- Isoquant is similar to an indifference curve in consumer theory, but for producers. It shows different combinations of inputs that yield the same level of output.
- Level of output remains constant along an isoquant. As you move along the curve, the combination of labor and capital changes, but the output stays the same.
Therefore, the key feature that is constant along an isoquant is the level of output.
Thus the correct answer is (B)
