Question

Match the following.

\[ \begin{array}{|c|l|c|l|c|l|} \hline \text{List-I} & & \text{List-II} & & \text{List-III} & \\ \hline \text{I} & \text{Manganese} & \text{A} & \text{Helps in anion-cation balance} & \text{P} & \text{Brown spots with chlorotic veins} \\ \hline \text{II} & \text{Zinc} & \text{B} & \text{Uptake and } Ca^{++}\text{ utilization} & \text{Q} & \text{Mottled leaf disease} \\ \hline \text{III} & \text{Boron} & \text{C} & \text{Needed for auxin synthesis} & \text{R} & \text{Heart-rot in beets} \\ \hline \text{IV} & \text{Chlorine} & \text{D} & \text{Activation of IAA oxidase} & \text{S} & \text{Bronzing in legumes} \\ \hline \end{array} \]

• A. I-A-S; II-B-R; III-C-Q; IV-D-P
• B. I-B-R; II-A-S; III-C-Q; IV-D-P
• C. I-D-P; II-C-Q; III-A-S; IV-B-R
• D. I-D-P; II-C-Q; III-B-R; IV-A-S

Hint:

Remember these important mineral functions: \[ \boxed{ \begin{aligned} &\text{Zn} &&\rightarrow \text{Auxin synthesis} &\text{Mn} &&\rightarrow \text{IAA oxidase activation} &\text{B} &&\rightarrow \text{Ca}^{2+}\text{ utilization} &\text{Cl} &&\rightarrow \text{Anion-cation balance} \end{aligned} } \]

Answer 1

The Correct Option is D

Step 1: Recall the physiological roles and deficiency symptoms. \[ \boxed{ \begin{aligned} \text{Manganese} &\rightarrow \text{Activates IAA oxidase} \rightarrow \text{Brown spots with chlorotic veins} \text{Zinc} &\rightarrow \text{Needed for auxin synthesis} \rightarrow \text{Mottled leaf disease} \text{Boron} &\rightarrow \text{Ca}^{2+}\text{ uptake and utilization} \rightarrow \text{Heart-rot in beets} \text{Chlorine} &\rightarrow \text{Anion-cation balance} \rightarrow \text{Bronzing in legumes} \end{aligned} } \]

Step 2: Match the lists. \[ \boxed{ \begin{aligned} \text{I} &\rightarrow D-P \text{II} &\rightarrow C-Q \text{III} &\rightarrow B-R \text{IV} &\rightarrow A-S \end{aligned} } \]

Step 3: Choose the correct option. Hence, the correct option is \[ \boxed{(D).} \]
