Question

Match the LIST-I with LIST-II and choose the correct answer from the options given below: \[ \begin{array}{|l|l|} \hline \textbf{LIST I} & \textbf{LIST II} \\ \hline A. \ \text{Correlation Coefficient value lies between} & I. \ \text{For Getting the Higher Precision} \\ B. \ \text{Standard Deviation} & II. \ \text{Unitless Measure of Dispersion} \\ C. \ \text{Larger Samples} & III. \ \text{-1 to +1} \\ D. \ \text{Coefficient of Variation} & IV. \ \text{Best Measure of Dispersion} \\ \hline \end{array} \]

• A. A - II, B - I, C - IV, D - III
• B. A - I, B - III, C - IV, D - II
• C. A - II, B - I, C - III, D - IV
• D. A - III, B - IV, C - I, D - II

Hint:

Remember the rule: Apple = Tongue grafting, Litchi = Air layering, Ber = Hardwood cuttings, Grapes = T-budding.

Answer 1

The Correct Option is C

Step 1: Apple.
Apple is commercially propagated by tongue grafting, hence A - II.
Step 2: Litchi.
Litchi is propagated by air layering, hence B - I.
Step 3: Ber.
Ber is propagated by hardwood cuttings, hence C - III.
Step 4: Grapes.
Grapes are commercially propagated by T-budding, hence D - IV.
Step 5: Conclusion.
So, the correct matching is: A - II, B - I, C - III, D - IV.
