Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Quantitative analysis in spectroscopy (like Flame Photometry or Fluorescence) relies on the relationship between signal intensity and concentration.
Step 2: Meaning
A directly proportional relationship means that if the concentration doubles, the measured emission intensity also doubles.
Step 3: Analysis
At low concentrations (like 5 to 10 ppm), the emission intensity ($I$) is generally related to concentration ($C$) by the equation $I = kC$.
Step 4: Conclusion
This indicates a directly proportional relationship within the linear range of the instrument. Final Answer: (b)
