Explanation
Coercivity is the correct answer because it measures the strength of the magnetic field required to demagnetize a storage medium - a higher coercivity means the medium resists unwanted demagnetization and holds data more reliably over time.
Magnetic Field (A) refers to the force field produced by a magnet, not the medium's capacity to resist losing its magnetization. Orientation (C) describes the alignment direction of magnetic particles during recording, not the medium's retention strength. Static Force (D) is not a standard magnetic storage concept and acts as a distractor borrowing from electrostatics.
Memory tip: Think of coercivity as the medium's "coercion resistance" - how hard it is to coerce the medium into changing its stored data. High coercivity = stubborn storage that won't forget.
