With which field was the term 'Rai' connected in Sher Shah's period?

Correct answer: (b) Revenue

Explanation

In Sher Shah's land revenue system the rai was a schedule of crop rates. Land was measured and divided into three classes (good, middling and bad). The average produce of each crop over the three classes was worked out, and the state took about one-third of it as revenue, in cash or in kind.

Each peasant got a patta (a deed stating his land and the revenue due) and signed a qabuliyat (accepting the terms).
