How can a human teacher connect a child's personal problem with class learning?

Correct answer: He can explain the doubt and turn it into a discussion for the class

The governing concept is responsive, interactive teaching. A child’s doubt is personal at first, but a human teacher can listen carefully, identify the underlying difficulty, explain it in an accessible way, and then invite the whole class to examine the idea. This converts an individual problem into a shared learning opportunity; other students may contribute examples, ask related questions, or learn from the explanation. Option A is therefore correct because it shows both personal attention and group learning. Options B and C remove the educational value of the doubt, while D avoids teaching altogether. A mechanical system may deliver a fixed response, but a human teacher can adapt the response to the child and the class.
