  1. Exclusive ownership of a critical raw materialAnswer
  2. B
    Statutory grant of legal monopoly privilege
  3. C
    Natural monopoly derived from extensive economies of scale
  4. D
    Artificial entry barrier created by product differentiation

Answer

Exclusive ownership of a critical raw material
Exclusive ownership or control of a key raw material prevents rival firms from producing the product, thereby securing a monopoly position for the firm that owns the essential input resource.

Step-by-Step Solution

1
Identify the key factual premise in the scenario
The firm holds sole ownership of the single commercially viable deposit of a vital input required for production.
Determining the origin of market dominance requires locating where the barrier to entry originates.
2
Categorize the entry barrier using economic taxonomy of monopoly sources
When a single firm controls the entire supply of an indispensable raw material, potential rivals cannot acquire the inputs needed to enter the industry.
This establishes a structural barrier rooted directly in natural resource control rather than legal patents or scale economies.

Key Concept

Control of essential raw materials as a source of monopoly power
