Which sets of angles listed are complementary in this diagram?

An image shows that line A B intersects line C D at a 90 degree angle at point E. Ray E F extends from line A B at point E, within the angle A E D. Ray E G extends from the line A B at point E, within the angle A E C.
A)<AEF and <FED, <AEG and <CEG
B)<AEG and <CEG, <CEG and <CEB
C)<AEF and< FED, <FED and <DEB
D)<AEG and <AED, <FED and DEB

The correct answer is C) <AEF and <FED, <FED and <DEB.
