B)white holes
C)gravitational redshifts
D)jets and accretion disks

Question

Quizplus · Accepted Answer

Jets and accretion disks are commonly observed as mechanisms for extracting energy from compact objects, such as black holes and neutron stars. These jets and disks are formed as matter is funneled onto the object, releasing gravitational potential energy in the process. The energy released can be observed in the form of radiation, such as X-rays and gamma-rays. Time dilation and gravitational redshifts may be involved in the observations of these objects, but they are not direct mechanisms for energy extraction. White holes, on the other hand, are hypothetical objects that have never been observed and are not considered to be involved in energy extraction.
