In the given question, a statement of Assertion is followed by a statement of Reason. Mark the correct answer. 

Assertion: In medieval India in cases of excessive revenue demands, if a compromise was not possible, the peasants deserted the village.

Reason: The relatively easy availability of uncultivated land and the competition over labour resources made this an effective weapon in the hands of cultivators.

Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.

In cases of excessive revenue demands, the panchayat often suggested a compromise. In cases where reconciliation failed, peasants took recourse to more drastic forms of resistance, such as deserting the village. The relatively easy availability of uncultivated land and the competition over labor resources made this an effective weapon in the hands of cultivators.
