Which type of motor task consists of discrete movements combined in sequence?

• A. Open
• B. Discrete
• C. Serial
• D. Continuous

Answer: (C)

This is about how motor tasks are organized by movement structure. A discrete movement has a clear start and end, like a single reach or a single button press. A continuous task has no distinct end, like running. A serial task is a sequence of discrete movements that must be performed in a specific order to complete the overall action. When movements are discrete but you must perform several of them in a row to achieve a goal, that’s a serial task. For example, typing a short word or playing a short melody involves multiple discrete actions in a set order. So the description fits a serial task.
