Question

Which of the following statements (with respect to compass traversing) are correct? 

A. True meridian at a station is constant. 
B. True meridian passing through different points on the earth surface converges towards the pole. 
C. The angle between the true meridian and the line is known as declination. 
D. The angle between the magnetic meridian and the line is known as azimuth. 
Choose the most appropriate answer from the options given below:

• A. A and B only
• B. A and C only
• C. B and D only
• D. C and D only

Hint:

Declination is the angle between true meridian and magnetic meridian; Azimuth is the angle between a line and true meridian.

Answer 1

The Correct Option is A

Step 1: Evaluate statement A.
The true meridian at a specific location is a constant reference. Therefore, statement (A) is accurate.

Step 2: Evaluate statement B.
True meridians originating from different geographical points converge at the geographic North Pole. Consequently, statement (B) is accurate.

Step 3: Evaluate statement C.
The angular difference between the true meridian and the magnetic meridian is termed declination. This definition does not pertain to the angle between the true meridian and an arbitrary line. Thus, statement (C) is inaccurate.

Step 4: Evaluate statement D.
The angle between a given line and the true meridian is defined as azimuth. This definition does not involve the magnetic meridian. Therefore, statement (D) is inaccurate.

Step 5: Final Assessment.
Statements A and B are the only correct propositions.
