True meridian: Geographic North pole and the south pole is the called the earth true meridian.

Magnetic meridian: The magnetic north pole and south pole direction is called Magnetic meridian.

THE MAGNETIC MERIDIAN CHANGES WITH TIME, so it not good to preferred in fieldwork.

The true meridian (geographic north-south pole direction) remains constant always.

So, the answer is "C".

According to me, the question should be.

True meridian are the line passing from north and south pole of the earth.

@All. Understand the question clearly.

It is asking why we refer to the true meridian over the magnetic meridian.

True meridian doesn't change over time while the magnetic meridian change through time. Question is confusing.

@all.

The Question is True meridians are generally preferred, WHY?

Because they remain constant every time.

True meridian remain constant, so readings also remain constant. So true meridian is preferred.

True meridian also converges at a point, so what should be the right one?

As magnetic meridian change with time option must be B.
