isabella was standing directly below a power line, and her compass failed to give an accurate reading.

a
a compass works with a magnetic field, and the electric current running through the lines above it would interfere with the magnetic field.
b
the compass works because of an electric field, and the electric current running through the lines above would interfere with the electric field.
c
the compass works because of a gravitational field, and the magnetic current running through the lines above would interfere with the gravitational field.
d
a compass works because of a magnetic field, and the magnetic current running through the power lines above it would interfere with the magnetic field below it.
