An ideal blackbody is an object that .a. absorbs most of the energy that strikes it. b. only absorbs energy at ultraviolet ("black light") wavelengths. c. absorbs all the energy that strikes it. d. absorbs a little of the energy that strikes it. e. absorbs exactly half of the energy that strikes it.

c. absorbs all the energy that strikes it.

Explanation:

An ideal black body is an object that absorbs every light energy (irrespective of the wavelength and direction) that strikes it without reflecting any in return.

Such objects or bodies usually appear perfectly black and will only emit radiation when heated to a very high temperature.
