In the vicinity of Mumbai, a number of specialised towns have been developed. Match the lists of specialisation with towns and select the correct answer using the codes given below the lists

List I (Towns) | List II (Specialisation)
I. Alibag | (A) Fishing Centre
II. Balapur | (B) Holiday resort
III. Nhava Sheva | (C) Petro-chemical complex
IV. Ratnagiri | (D) Port

The correct answer is Option 2 (I-B, II-C, III-D, IV-A). This matching correctly identifies the functional specialisation of towns near Mumbai based on their economic and geographical significance.

• Alibag (I-B): Known for its scenic beaches and proximity to Mumbai, it is primarily developed as a popular holiday resort and weekend getaway.
• Balapur (II-C): Located in the industrial belt, it is a significant hub for the petro-chemical complex, housing major industrial units.
• Nhava Sheva (III-D): Home to the Jawaharlal Nehru Port Trust (JNPT), it is India's largest container port, designed to relieve pressure on the Mumbai Port.
• Ratnagiri (IV-A): While diverse, it is historically and economically established as a major fishing centre along the Konkan coast.

Options 1, 3, and 4 are incorrect because they mismatch these established functional identities, such as incorrectly attributing port status to Alibag or holiday resort status to Nhava Sheva.
