Which of the following options is correct in accordance with the cathode ray tube?
CRTs are brighter than LCDs.
CRTs can operate at any resolution and at any aspect ratio.
CRTs are the most expensive display device till current date.
None of the above
Correct Answer :
C. CRTs are the most expensive display device till current date.
All the other options are incorrect for a Cathode Ray Tube. The only option (b.) is correct. Because the CRTs are not brighter than LCDs. Also, CRTs are very cheap. The only true option is: the CRTs can operate at any resolution and any aspect ratio.
