Step 1: Recall the weather elements and instruments.
- Temperature is measured by a Thermometer (IV).
- Rainfall is measured using a Rain gauge (III).
- Wind velocity is measured using an Anemometer (II).
- Dew is measured with a Dew gauge (I).
Step 2: Construct the correct matching.
\[
\begin{aligned}
(A) &\rightarrow (IV) \text{Thermometer for Temperature}
(B) &\rightarrow (III) \text{Rain gauge for Rainfall}
(C) &\rightarrow (II) \text{Anemometer for Wind velocity}
(D) &\rightarrow (I) \text{Dew gauge for Dew}
\end{aligned}
\]
Step 3: Verify against the options.
Comparing with the given options, only Option 1 matches the correct sequence.
Final Answer: \[ \boxed{\text{The correct answer is 1. (A) - (IV), (B) - (III), (C) - (II), (D) - (I)}} \]
