Consider the following statements based on this graph: 1. Yield rate is zero at B and C

Question

The yield versus fertilizer input is shown in the graph.

Consider the following statements based on this graph:

1. Yield rate is zero at B and C

2. There is no yield with no fertilizer input

3. The yield is minimum at D

4. The yield is neither minimum nor maximum at C

Which of the above statements are correct?

(a) 1, 2 and 4 (b) 3 and 4 (c) 2 and 3 (d) 1, 3 and 4

Answer 1

(b) From the graph, it can be seen that yield rate is not zero at B and C. With no fertilizer input, yield is 20. Yield is clearly minimum at D, i.e., 8. At C, yield is 20 and it is neither maximum nor minimum. So clearly option 3 and 4 are correct.
