Correct Answer - Option 3 : 01°E
Concept-
The magnetic bearing of sun at noon is 180˚.
Given Data and Calculation-
The magnetic bearing of sun at noon is 179˚, but it should be 180˚.
So True bearing = Magnetic bearing + magnetic declination
180 ° = 179 ° + MD
Magnetic declination = 1˚ E (as it is positive)
