The Correct Option is C

Solution and Explanation

Concept:
In production theory, a firm uses inputs such as labour and capital to produce output. An isoquant shows all possible combinations of two inputs that produce the same level of output.

Step 1:
Understand the meaning of isoquant.
The word isoquant has two parts: \[ \text{Iso} = \text{same} \] \[ \text{Quant} = \text{quantity} \] So, isoquant means: \[ \text{same quantity of output} \]

Step 2:
Apply the definition.
The question says: \[ \text{combinations of two inputs that produce the same level of output} \] This is exactly the definition of an isoquant.

Step 3:
Eliminate other options.
Isocost shows combinations of inputs that cost the same amount. Indifference curve shows combinations of goods giving the same satisfaction to a consumer. Budget line shows combinations of goods that a consumer can buy with given income. So, these are not correct.

Step 4:
Final conclusion.
Therefore, the correct answer is: \[ \boxed{\text{Isoquant}} \] Hence: \[ \boxed{\text{(C)}} \]
