Final answer:
The correct answer is c. Pointing, as it is a clear and universal gesture for indicating locations and directions, helping to avoid miscommunication in a classroom setting.
Step-by-step explanation:
The key move when giving commands involving location is c. Pointing. Pointing is a universal gesture that helps to indicate direction or draw attention to a particular spot or thing, which can be critical when verbal instructions are not sufficient or when there is a language barrier. In the context provided, the teaching experience highlights the cultural nuances of nodding in the classroom, where a nod can be interpreted as an indication of correctness or incorrectness, leading to confusion. This underscores the importance of using clear, unambiguous gestures like pointing when giving commands related to location, to ensure understanding and avoid miscommunication.
