There were four main reasons for the brief rebellion in Wayanad in 1812. These reasons agree with all the given statements:
(i) Excessive taxation by the British:
Connection: The British East India Company imposed unjust and excessive taxes on the tribals of Wayanad which was the main cause of the rebellion.
(ii) Forced to pay tax in cash:The British changed the way taxes were paid in goods or other goods till then. Insisting on payment of taxes only in cash (coins) made farmers and tribals miserable.
(iii) Expropriation of agricultural land of defaulters:
The British seized and auctioned the agricultural land etc. of those who could not pay taxes in cash. This led to evictions and protests.
All these three reasons are factors that directly led to the riots. Therefore, all these three statements are true.
