Q.34) Why are the R-Y and B-Y signals shifted 33° counterclockwise?:
- A.
  
  A. To align R-Y and B-Y with their respective primary colors.
- B.
  
  B. To align R-Y and B-Y with their respective complementary colors.
- C.
  
  C. R-Y was shifted to min and B-Y was shifted to max color acuity, respectively for human vision.
- D.
  
  D. R-Y was shifted to max and B-Y was shifted to min color acuity, respectively for human vision.
Correct Answer
D. D. R-Y was shifted to max and B-Y was shifted to min color acuity, respectively for human vision.

Explanation
The R-Y and B-Y signals are shifted 33° counterclockwise to maximize the color acuity for human vision. This means that the R-Y signal is shifted to maximize the sensitivity to red colors, while the B-Y signal is shifted to minimize the sensitivity to blue colors. By aligning the signals in this way, the resulting image will more accurately represent the primary colors and their respective intensities, improving the overall color perception for human viewers.
