Explanation:

Taglines are crucial for brand identity in the banking sector. The slogan 'With You all the Way' is the well-known and long-standing tagline of the State Bank of India (SBI), one of the largest and oldest commercial banks in India. This tagline emphasizes its commitment to customers throughout their financial journey. Option (1) Reserve Bank of India is the central bank and does not typically use such a consumer-facing tagline. Options (3) Punjab National Bank and (4) Bank of India have their own distinct taglines. Therefore, (2) State Bank of India is the correct answer.
