The alignment and stability of the Earth's magnetic field over geological times can be described by stating that the Earth's magnetic axis
A)   is inclined to the planet's spin axis; this alignment varies; and the field has reversed frequently in geological times.
B)   is closely aligned to the Earth's spin axis and has remained this way since early in the Earth's history.
C)   has had a slowly varying inclination with respect to the Earth's spin axis with no abrupt changes, such that the Earth's magnetic poles have drifted slowly throughout its geological history.
D)   has a fixed alignment of about 11° with respect to the Earth's spin axis but has flipped or reversed completely many times in geological times.
