Runners or Tracks are described as top and bottom.

• A. Upright studs
• B. U-shaped top and bottom members
• C. Diagonal bracing
• D. Fin plates

Answer: (B)

Runners or tracks are the horizontal members that form the top and bottom boundaries of a stud wall in steel framing. They are U-shaped channels that the vertical studs slide into and are fastened to, providing a stable path and anchor points from floor to ceiling. That channel shape is what makes them fit the role of top and bottom members, hence the description as U-shaped top and bottom members.

Upright studs are the vertical members, so they aren’t the tracks. Diagonal bracing serves to resist lateral loads rather than forming the track system. Fin plates are different connection components, not the horizontal tracks that guide and hold the studs in place.
