The correct option is A Diversified investments
Diversified investments in various fields help farmers to overcome crop failure. Apart from the farm lands owned by them, farmers have other assets that yield good returns on their investments. Farmers utilize profits from these additional assets to acquire more land and lease it to small farmers for cultivation. Farmers also borrow money from the banks to buy the most sophisticated machinery and rent them out to surrounding villages. Thus, big farmers remain unaffected by crop failure.
