Explanation:

The administrative machinery of the Aryans in the Rig Vedic period functioned with the tribal chief, for his successful leadership in war, at the centre. He was called rajan. It seems that in the Rig Vedic period, the king‘s post had become hereditary. However, the rajan was a kind of chief and did not exercise unlimited power, having to reckon with the tribal organizations.

• We have traces of the election of the king by the tribal assembly called the samiti. The king was called the protector of his tribe. He protected its cattle, fought its wars, and offered prayers to the gods on its behalf.
• Several tribal or kin-based assemblies such as the sabha, samiti, vidatha, and gana are mentioned in the Rig Veda. They exercised deliberative, military, and religious functions. Even women attended the sabha and vidatha in Rig Vedic times.
• The king did not maintain any standing army, but in times of war he mustered a militia whose military functions were performed by various tribal groups called vrata, gana, grama, sardha. By and large, it was a tribal system of government in which the military element was strong. Hence statement 2 is not correct.
