Under which of the following conditions may parents instruct their children to pay for their torts?

The correct answer indicates that parents may instruct their children to pay for their torts when the child is acting on behalf of the parent. This scenario typically arises under the legal doctrine of vicarious liability, where an individual (often a parent) can be held responsible for the actions of another (the child) performed in the course of executing a task or fulfilling a role for the parent. It is essential in understanding that when children act in circumstances that directly align with the interests or instructions of their parents, the parents can not only be liable for those actions but may also direct the child to assume responsibility for any resulting torts.

This option emphasizes the concept that the child is an agent carrying out the parent's wishes, and thus any tortious acts committed in this capacity may, in part, be the liability of the parents. The relationship between principal and agent plays a crucial role in such situations, indicating that the actions taken by the child in service to the parent create a direct link to liability.

The other choices outline situations that do not meet the necessary legal criteria for the instruction to pay for torts. For instance, when a child acts alone or negligently without the influence or direction of the parent, there isn't a clear linkage to parental responsibility under
