A measuring tape is the appropriate tool for determining the distance covered in a long jump. It provides precise measurements from the point of departure to the landing zone.
- Option (a): A stopwatch measures elapsed time, not spatial extent.
- Option (b): A height chart is used for vertical measurements, not horizontal distances.
- Option (d): A weighing scale is used to determine mass.
Therefore, a measuring tape is the correct instrument for long jump distance measurement.
