Explanation:

Only statements 1&2 are correct.

Statement 3 is incorrect: The Ministry of Home Affairs has classified 75 tribal groups from 18 states of the country and union territory of Andaman and Nicobar Islands of India as Particularly Vulnerable Tribal Groups.

• Ministry of Tribal Affairs has implemented the scheme of “Development of PVTGs” which covers 75 Particularly Vulnerable Tribal Groups (PVTGs) for their comprehensive socio-economic development.

• Under the scheme, State Governments submits Conservation-cum-Development (CCD) plans on the basis of their requirement.

• 100% grants-in-aidare made available to States as per the provisions of the scheme.

Particularly Vulnerable Tribal Groups (PVTGs)

• In India, tribal population makes up for 6% of the totalpopulation.

• PVTGs are more vulnerable among the tribal groups. Due to this factor,more developed and assertive tribal groups take a major chunk of the tribal development funds because of which PVTGs need more funds directed for their development.

• In 1973,the Dhebar Commission created Primitive Tribal Groups (PTGs) as a separate category, who are less developed among the tribal groups. In 2006, the Government of India renamed the PTGs as PVTGs.

• In this context, in 1975,the Government of India initiated to identify the most vulnerable tribal groups as a separate category called PVTGs and declared 52 such groups, while in 1993 an additional 23 groups were added to the category, making it a total of 75 PVTGs out of 705 Scheduled Tribes.

• PVTGs have some basic characteristics -they are mostly homogenous, with a small population, relatively physically isolated, absence of written language, relatively simple technology and a slower rate of change

• Among the 75 listed PVTG’s the highest number are found in Odisha.

Hence option 2nd is correct.
