C Correct answer
Explanation

The Vertical Blanking Interval (VBI) is the portion of a TV signal between frames that can be used to transmit text data like closed captions, teletext, or other information. This interval exists because early CRT TVs needed time to reset the electron beam. 'Control Interval,' 'Word Interval,' and 'Temp Space' are not technical terms in television broadcasting.
