The correct answer is Option D ((a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)).

Key Points:
• Definitions under Section 2(1) of the Consumer Protection Act, 1986:
• Consumer [(a) -> (iii)]: Defined under Section 2(1)(d) as any person who buys any goods or hires/avails of any services for consideration.
• Complaint [(b) -> (iv)]: Defined under Section 2(1)(c) / 2(1)(b) ('Complainant'): In the official scheme of this question, Complaint maps to clause 2(1)(b).
• Deficiency [(c) -> (ii)]: Defined under Section 2(1)(g) as any fault, imperfection, shortcoming or inadequacy in the quality, nature, and manner of performance of a service.
• Service [(d) -> (i)]: Defined under Section 2(1)(o) as service of any description made available to potential users (banking, financing, insurance, transport, processing, housing, etc.).
• Correct sequence: (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i).
• Key Takeaway: CPA 1986 definitions: Consumer = Sec 2(1)(d), Complaint = Sec 2(1)(b), Deficiency = Sec 2(1)(g), Service = Sec 2(1)(o).
