Solution

The correct option is B B
The close continuous curves in a magnetic field are called magnetic lines of force. Curved lines are used to represent a magnetic field, drawn such that the number of lines relates to the magnetic field's strength at a given point and the tangent of any curve at a particular point is along the direction of magnetic force at that point.
The magnetic lines of force are uniform and strong at the point C and they diverge as they move towards points A and B and the distance between the lines increases. At this point when we consider points A and B, the magnetic lines of force at B seem to be more divergent than A. Eventually, the strength of the magnetic field is weaker at B where the lines are far and they strengthen as closeness increases.
Hence, the magnetic field is weakest at the point B compared to A and C.
