Answer - A - Speaker delay is used to compensate for speaker distance when configuring surround sound systems.

Key Takeaway: You should adjust the delay between the front and rear speakers appropriately when calibrating a surround system. If the delay is too long, it may result in an echoed, unnatural surround field, or cause imaging shifts in the sound-field. If the delay is too short, it may result in a flat 2-dimensional sound field between the front and rear speakers. A 1 ms delay corresponds to 1.1 ft of increased distance from the rear speakers relative to the listening position.
