As earth’s magnetic pole moves, the magnetic declination in a given location will a. stay the same. b. switch to point south. c. change. d. return to zero.

Option ' C ' is correct.

Explanation:

Magnetic declination is referred to the angle formed by Magnetic Median with the Geographical Median.

Here, Magnetic Median is when a magnetic field is left free in the air, it always points to the north south direction without considering any other attracting force.

And Geographical Meridian is referred to the plane crossing the north and south pole of earth.

So, magnetic declination is completely depends upon the earth' s magnetic pole .

If magnetic pole of earth moves, the magnetic declination in a given location definitely changes.

Hence, option 'C' is correct.
