Step 1: Understanding the Concept:
Different equipment are used to measure different plant physiological parameters.
We need to match each equipment with its measured parameter.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the functions of each equipment.
Step 3: Detailed Explanation:
IRGA (Infrared Gas Analyser): measures photosynthetic rate (A-III).
Porometer: measures transpiration rate (B-I).
Osmometer: measures osmotic potential (C-IV).
Pressure bomb system: measures water potential (D-II).
Thus, A-III, B-I, C-IV, D-II is the correct matching.
Step 4: Final Answer:
The correct matching is A-III, B-I, C-IV, D-II.
Hence, the correct option is (B).
