Which of the following is also a unit of measurement for magnet strength?

Explanation:
Magnet strength is described by magnetic flux density, B. In the CGS system, B is measured in gauss, with 1 gauss equal to 10^-4 tesla, so gauss directly quantifies how strong a magnetic field is in that system. The tesla serves the same role in the SI system, so it also measures the field’s strength, but the question targets the CGS unit. Oersted measures magnetic field intensity H in CGS, which is a related but different quantity, and ampere-turns quantify magnetomotive force rather than the field itself. So gauss is the direct unit for magnet strength in this CGS context.
