Question

Match List-I with List-II

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: Instrument Functions.
- An alidade is used in chain surveying to sight and measure line direction.
- Arrows mark instrument positions or sight lines in leveling.
- A bubble tube ensures instrument levelness in plain table surveying.
- Stadia hairs measure horizontal distances in theodolite surveying.

Step 2: Matching Conclusion.
The correct pairing is: (A) - (III), (B) - (I), (C) - (II), (D) - (IV). Therefore, option (1) is correct.

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