In case of natural monopoly
(i) C(q1+q2)C(q_1 + q_2) <C(q1)+C(q2)< C(q_1) + C(q_2)
(ii) C(q)q\frac{C(q)}{q} >C(q+Δq)q+Δq> \frac{C(q + \Delta q)}{q + \Delta q}
(iii) C(q)q\frac{C(q)}{q} <C(q+Δq)q+Δq< \frac{C(q + \Delta q)}{q + \Delta q}
(iv) C(q1+q2)C(q_1 + q_2) >C(q1)+C(q2)> C(q_1) + C(q_2)

Answer and explanation

Correct answer A

Natural monopoly is associated with subadditive costs: producing the combined output in one firm costs less than splitting it between firms. Declining average cost gives the relationship in statement (ii), while statements (iii) and (iv) reverse these cost relationships.
