The condition that will give the most benefits is (c) – Farmers use quality seeds, adopt irrigation, use fertilizer, and use crop protection measures.
Explanation:
Using high-quality seeds is a good start, but to maximize yield, farmers need to combine it with other practices like irrigation, fertilization, and crop protection.
Why other options are not as beneficial:
(a) This option only utilizes high-quality seeds, which is not enough for optimal crop production without additional measures like irrigation and fertilization.
(b) While this option includes irrigation and fertilization, using ordinary seeds might limit the potential yield compared to using high-quality seeds.
