Best answer
The correct answer is (c) Black Holes

The explanation is: In close binary systems containing black holes or neutron stars, X-rays are created. In these systems, the more massive and compact stellar remnant strips material from its companion star to form a disk of extremely hot X-ray-emitting gas as it spirals inward.
