Please explain this question explain
Dear Student,
We know that The plane which is passing through magnetic poles at a certain place is called the magnetic meridian and the angle between these two planes is called the declination at that place.
And Isogonic lines of the magnetic map represent the lines joining the places with the equal declination.
So, option 2 is correct
Regards
