A philosopher argues that conscious states (in the sense that there is phenomenological experience/qualia) is a logically necessary condition for accomplishing any goal at least well as a human. This means that:

A. A machine may not accomplish any goal at least well as a human but may be conscious

B. Epiphenomenalism is most likely to be false

C. A machine cannot in principle accomplish any goal at least well as a human

D. Consciousness is also a logically sufficient condition for accomplishing any goal at least well as a human
