Explanation:

Indian Railway collects over 100 Terabytes of data every year, yet it is hardly analysed to gain business insights. Towards this direction, the Railway Budget 2016-17 has proposed to set up a dedicated, cross functional team called Special Unit for Transportation Research and Analytics (SUTRA) for carrying out detailed analytics leading to optimised investment decisions and operations. SUTRA will be comprised of professional analysts and best-in-class decision support systems. Its core function will be data-mining and data backed decision making.

Initiatives by Ministry of Railways

1. SRESTHA - New R&D organisation to serve the future technology needs of Railways.

2. SUTRA – A special unit for Transportation Research and Analytics. The team will be involved in World class data analytics, simulation softwares, network optimisation and decision support systems.

3. NIVARAN – A grievance redressal portal and first IT application in Rail Cloud for resolving service related grievances of serving and former railway employees.

Hence option 1st is correct.
