D) Apparent. Meaning the way it appears to us. Absolute is the magnitude as viewed from a set distance for all stars. Generally as it would be seen from ten parsecs.

D) Apparent

For example, the Sun has an apparent magnitude of -26.7 (very bright in the sky),
and an absolute magnitude of +4.8 (visible, but not very bright).
