The correct options are
B asking small farmers to keep cows for a living.
C educating the farmers about loans.
D increasing the wages of agricultural labourers.
Rural livelihood can be better by stopping illegal fishing activities during monsoon so that fishes can breed. Cows can help make an everyday living by giving milk, which can be used to sell or to consume. Educating farmers can help them save money and smartly choose for limited loans. Increasing wages of agricultural labourers can boost them to take up this job and work harder.
