Answer - B - The standard aspect ratio of HDTV is 1.78:1.

Key Takeaway: The aspect ratio is the fractional relation of the width of a video image compared to its height. All older TVs and computer monitors use an aspect ratio of 4:3 that is square in shape with only 33 percent wider than it was high. The 16:9 or 1.78:1 aspect ratio is the native aspect ratio for HDTV programming; it is 78 percent wider than it is tall.
