When is Minimum Support Price (MSP) declared by the government?
Minimum Support Price (MSP) is a kind of guarantee of a minimum price for the agricultural produce in India. The MSP is announced by the Government of India at the beginning of the sowing season for some crops to protect the producers i.e. farmers - against acute fall in price during bumper production years.
So the announcement of the MSP motivates the farmers to sow more crops every year.
Hence Option C is the correct answer.
