Touchdown zone markings may be grouped in which of the following sets of counts for the rectangular bars?

Touchdown zone markings give pilots distance cues by using groups of rectangular bars on both sides of the runway centerline. The number of bars in each group is limited to 1, 2, or 3, and these groups appear at fixed intervals from the threshold up to 3,000 feet down the runway. Therefore, the sets of counts that can appear for a single group are 3 bars, 2 bars, or 1 bar. The correct choice reflects that range, and there would never be a 0-bar group or a group with more than 3 bars. Long runways may show all three groups; shorter ones may omit some.
