Explanation:

Airtel Payment Bank launched the 'Suraksha Salary Account' specifically designed for the employees of Micro, Small, and Medium Enterprises (MSMEs) to provide them with financial security and easy access to banking services. Therefore, option A is correct. Option B, State Bank of India, is a major public sector bank but did not launch this particular product. Option C, Jammu & Kashmir Bank, primarily serves its regional customers. Option D, Paytm Payment Bank, is another payment bank, but Airtel Payment Bank was the one that introduced this specific 'Suraksha Salary Account'. Thus, B, C, and D are incorrect.
