Answer:
"Does he turn off the light?"
Explanation:
When we want to turn a statement like "He turns off the light" into a question, we use a specific way of rearranging the words. First, we add the word "Does" at the beginning of the sentence. Then, we switch the places of the subject ("he") and this new word ("Does"). After that, we use the base form of the main verb ("turn off") without changing it. So, "He turns off the light" becomes "Does he turn off the light?" This is how we ask a yes/no question in English by using these special words at the beginning of the sentence and changing the word order a bit.
