Which of the following is not a direct effort to increase agricultural production?

The National Youth Service Corps (NYSC) is not a direct effort to increase agricultural production. The NYSC is a one-year mandatory program for Nigerian graduates under the age of 30, aimed at promoting national unity and development. While some corps members may be deployed to work on agricultural projects during their service year, the program itself is not focused solely on agricultural production. On the other hand, options A, B, and C are all direct efforts to increase agricultural production. Operation Feed the Nation was a program launched in Nigeria in 1976 to increase food production and reduce dependence on imported food. The use of improved seedlings and increased loans to farmers and co-operative societies are also direct efforts to increase agricultural production by improving the quality of inputs and increasing access to credit for farmers.
