Which of the following was true of society in the Rig Vedic (Early Vedic) period?

The correct choice is: Widows could remarry

In the Rig Vedic period women had a fairly high status. Widows could remarry, and levirate (niyoga) was practised.

Child marriage and sati were not customs of this period. Polygamy was known, especially among chiefs, so it was not ‘unknown’.

Hence the answer is ‘Widows could remarry’.
