Match the LIST-I with LIST-II
\[
\begin{array}{|l|l|}
\hline
\textbf{LIST I (Vegetable crop)} & \textbf{LIST II (Variety)} \\
\hline
A. \ \text{Radish} & I. \ \text{Pusa Purple Long} \\
B. \ \text{Brinjal} & II. \ \text{Pusa Ruby} \\
C. \ \text{Tomato} & III. \ \text{Pusa Chetki} \\
D. \ \text{Pea} & IV. \ \text{Pusa Pragati} \\
\hline
\end{array}
\]
Step 1: Radish varieties.
Pusa Chetki is a famous early maturing radish variety developed by IARI, hence A → III. Step 2: Brinjal varieties.
Pusa Purple Long is a widely cultivated brinjal variety, hence B → I. Step 3: Tomato varieties.
Pusa Ruby is a popular tomato variety, hence C → II. Step 4: Pea varieties.
Pusa Pragati is an improved variety of pea, hence D → IV. Step 5: Conclusion.
Thus, the correct matching is A - III, B - I, C - II, D - IV.
