List-I	List-II
(A) Alidade	(III) Plain table surveying
(B) Arrow	(I) Chain surveying
(C) Bubble Tube	(II) Leveling
(D) Stadia hair	(IV) Theodolite surveying

Choose the correct answer from the options given below:

• (A) - (III), (B) - (I), (C) - (II), (D) - (IV)
• (A) - (I), (B) - (IV), (C) - (III), (D) - (II)
• (A) - (II), (B) - (III), (C) - (I), (D) - (IV)
• (A) - (III), (B) - (I), (C) - (IV), (D) - (II)

Hint:

Each surveying instrument has a specific purpose, such as sighting, leveling, or measuring, and is used accordingly.

Answer 1

The Correct Option is A

Step 1: Understanding Instruments.
- Alidade is used in chain surveying for sighting and measuring the direction of the line.
- Arrow is used in leveling to mark the instrument's position or sight line.
- Bubble tube is used in plain table surveying to ensure the instrument is level.
- Stadia hair is used in theodolite surveying to measure horizontal distances.

Step 2: Conclusion.
Thus, the correct matching is: (A) - (III), (B) - (I), (C) - (II), (D) - (IV). Therefore, option (1) is correct.

Final Answer: \[ \boxed{1. \, (A) - (III), (B) - (I), (C) - (II), (D) - (IV)} \]
