Total variable cost is the component of total cost that changes with output, so it fits the equation Total fixed cost = Total cost − X.

1. Relevant knowledge points and concepts
- Total Cost (TC) is the sum of all costs incurred in production.
- Total Fixed Cost (TFC) is the portion of TC that does not vary with output (rent, salaries of permanent staff, etc.).
- Total Variable Cost (TVC) varies with output (raw materials, hourly labor).
- Identity: TC = TFC + TVC. Rearranging gives TFC = TC − TVC.

2. Complete reasoning process step by step
- Start with the fundamental identity: TC = TFC + TVC.
- Subtract TFC from both sides: TC − TFC = TVC.
- The question gives TFC = TC − X. Compare this with the rearranged identity: TC − TFC = TVC, or equivalently TFC = TC − TVC.
- Thus X must be TVC to make the two expressions identical.

3. Intermediate steps (algebra)
- TC = TFC + TVC
- Rearranged: TFC = TC − TVC
- Given: TFC = TC − X
- Therefore equate: TC − X = TC − TVC → X = TVC

4. Why the correct answer is correct
- Because by definition total cost splits into fixed and variable parts. The only variable that subtracts from total cost to leave total fixed cost is total variable cost. Subtracting TVC from TC isolates the fixed portion.

5. Why the other options are incorrect
- Total profits: Profits are revenues minus costs, not a component of total cost; TC − Total profits is not a definition of TFC.
- Average total cost (ATC): ATC = TC/Q (per-unit), not a component you subtract from TC to yield TFC.
- Marginal cost (MC): MC is the change in TC for an extra unit, not an additive component of TC that sums to produce TFC when subtracted.

6. Conclusion
The correct answer is Total variable cost, which matches the provided answer.
