The Correct Option is A
Solution and Explanation
Step 1: Recall what each instrument measures.
A wind vane is a simple rotating instrument that lines up with the wind, so it shows the direction the wind is coming from.
A quantum sensor is a light sensor built to detect only the wavelengths plants use for photosynthesis, so it measures photosynthetically active radiation (PAR).
An anemometer has spinning cups or a propeller that turn faster in stronger wind, so it measures wind speed.
A barometer measures the weight of the air column above it, so it measures atmospheric pressure.
Step 2: Pair each instrument with its parameter.
Wind vane goes with wind direction, item (IV).
Quantum sensor goes with photosynthetically active radiation, item (I).
Anemometer goes with wind speed, item (II).
Barometer goes with atmospheric pressure, item (III).
Step 3: Check against the options.
This gives (A)-(IV), (B)-(I), (C)-(II), (D)-(III), which matches option 1 exactly.
The other three options swap at least one pairing, for example putting wind speed against the barometer or PAR against the anemometer, both of which are wrong.
Final Answer:
The correct matching is (A)-(IV), (B)-(I), (C)-(II), (D)-(III).
\[ \boxed{\text{Option 1}} \]
