A runner is awarded one base when:

• A. A foul fly is caught by the left fielder who then leaves the field of play by stepping with both feet into a dead-ball area.
• B. Attempting to advance at the time a ball becomes lodged in an offensive player's uniform or equipment.
• C. Both A & B.
• D. Neither A nor B.

Answer: (C)

The key idea is that certain events immediately make the ball dead and award runners one base. In these two situations, the ball is declared dead right away, so runners advance exactly one base.

First, on a foul fly that is caught, the batter is out, but if the fielder who made the catch then enters a dead-ball area, the ball is dead and runners are awarded one base. The critical point is that the ball becoming dead ends the live action and limits advancement to one base for the runners.

Second, if a live ball becomes lodged in a player's uniform or equipment, the ball is dead and runners are awarded one base. This prevents ongoing play from continuing with a ball that’s effectively out of play.

Since both scenarios result in a dead ball and a one-base award for runners, both are correct.
