Both option (1) and option (2) 

The correct answer is option 3. Both option (1) and option (2).

Nitrogen (N) and phosphorus (P) are two important non-metals that contribute to fertilizers' ability to promote plant growth . The green color of leaves is a result of nitrogen's role in leaf growth. The growth of seeds and fruits, as well as disease resistance, are both promoted by phosphorus.
