Explanation:

The various features of administration contained in the Sixth Schedule are as follows:

• The district and regional councils administer the areas under their jurisdiction. They can make laws on certain specified matters (not on all matters) like land, forests, canal water, shifting cultivation, village administration, inheritance of property, marriage and divorce, social customs and so on. But all such laws require the assent of the governor. 
• The tribal areas in the four states of Assam, Meghalaya, Tripura and Mizoram have been constituted as autonomous districts. Each autonomous district has a district council consisting of 30 members, of whom four are nominated by the governor and the remaining 26 are elected on the basis of adult franchise. 

Hence both statements are incorrect.
