Question

Match the LIST-I with LIST-II. \[ \begin{array}{|c|c|c|l|} \hline \text{LIST-I} & \text{Instruments} & \text{LIST-II} & \text{Use} \\ \hline A. & \text{Barometer} & I. & \text{Measures the angles} \\ \hline B. & \text{Pantograph} & II. & \text{Measures area of map} \\ \hline C. & \text{Sextant} & III. & \text{Enlargement and reduction of map} \\ \hline D. & \text{Planimeter} & IV. & \text{Measures air pressure} \\ \hline \end{array} \] Choose the correct answer from the options given below: 

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

Hint:

Important surveying instruments: \[ \boxed{ \begin{aligned} \text{Barometer} &\rightarrow \text{Air Pressure}, \text{Pantograph} &\rightarrow \text{Map Enlargement/Reduction}, \text{Sextant} &\rightarrow \text{Angle Measurement}, \text{Planimeter} &\rightarrow \text{Area Measurement}. \end{aligned} } \] Mnemonic: “Barometer--Pressure, Pantograph--Scale, Sextant--Angle, Planimeter--Area.”
