What is A's legal standing if he has allowed an individual to enter his property for a specific purpose but the individual does not adhere to that purpose?

A's legal standing is rooted in the concept of property rights and the principles of liability. When A allows an individual to enter his property, that permission is typically granted for a specific purpose. If the individual exceeds that permission and does not adhere to the specified purpose, they can lose the privilege of being on the property.

In this scenario, A retains the right to control access to his property. If the individual uses the property for a purpose that goes beyond what was initially agreed upon, A can pursue an action for trespass. Trespass is defined as an unauthorized entry onto another person's property, and since the individual's actions were not in alignment with the granted permission, they can be seen as trespassing.

This principle transforms the legal standing from a mere license to be on the property to a situation where the property owner can take action against the intruder. Therefore, the option stating that A can pursue action for trespass accurately reflects the legal implications of the individual's failure to adhere to the agreed purpose for their entry.
