Hint:

Bispyribac-Sodium is a widely known post-emergence herbicide specifically developed for rice fields. Using this popular pair can help you eliminate incorrect options instantly.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Chemical weed control depends on the selective action of herbicides.
Specific active ingredients are approved for post-emergence or pre-emergence control based on crop tolerance.

Step 2: Detailed Explanation:
Let us evaluate each crop-herbicide recommendation:
- Wheat: Clodinafop Propargyl is a highly selective post-emergence herbicide widely used to control grassy weeds like *Phalaris minor* (Canary grass) in wheat fields. (A - IV)
- Maize: Tembotrione is a highly selective post-emergence herbicide used to control broad-leaved and grassy weeds in maize. (B - III)
- Gram (Chickpea): Fluchloralin is a pre-plant incorporation (PPI) herbicide commonly recommended for pulses to control annual grasses and broadleaf weeds. (C - II)
- Rice: Bispyribac-Sodium is a popular broad-spectrum, post-emergence herbicide used to manage weeds in transplanted and direct-seeded rice. (D - I)
Thus, the correct match is A - IV, B - III, C - II, D - I.

Step 3: Final Answer:
This matching sequence is found in Option (B).
