Step 1: Understanding the Question:
This question tests knowledge of instruments used in meteorology and agrometeorology.
Step 2: Detailed Explanation:
PAR (Photosynthetically Active Radiation) (A): Measured by a Quantum sensor (II).
Canopy temperature (B): Measured by an IR-thermometer (IV).
Rainfall (C): Measured by a Pluviometer (I) (rain gauge).
Wind direction (D): Measured by a Wind vane (III).
Thus, the correct matching is A-II, B-IV, C-I, D-III.
Step 3: Final Answer:
Thus, the correct answer is A-II, B-IV, C-I, D-III, which corresponds to option (C).
