01 In a remote class, background noise, unrelated messages, and speaking out of turn show lack of what?
Answer and explanation
Correct answer: A. Digital etiquette and responsible communication
Explanation: Digital etiquette means behaving respectfully and responsibly in an online environment. Muting the microphone when not speaking, using the class chat for relevant messages, and waiting for one's turn reduce disturbance and help everyone learn. Spreadsheet formulas, print preview, and file extensions are technical features unrelated to behaviour in a remote class.
