The options analyze four different statements related to the yield versus fertilizer input based on a given graph.

Option 1: Suggests that the yield rate is zero at points B and C, there is no yield with no fertilizer input, and the yield is neither minimum nor maximum at C.

Option 2: Claims that the yield is minimum at point D and the yield is neither minimum nor maximum at C.

Option 3: Proposes that there is no yield with no fertilizer input, and the yield is minimum at D.

Option 4: State that the yield rate is zero at points B and C, the yield is minimum at D, and the yield is neither minimum nor maximum at C.

The correct answer is option 2, which means that according to the graph, the yield is minimum at point D and the yield at C is neither at its minimum nor maximum. In order to understand this, the student needs to carefully interpret the data shown in the graph. The correct option will accurately reflect the relationship between yield and fertilizer input as shown in the graph.
