The concept of conversion is directly associated with which of the following actions?

The concept of conversion pertains to the unauthorized taking of someone’s personal property and denying the owner of the use of that property. This is a legal term often associated with tort law, where the focus is on the wrongful possession or control over someone else's belongings. The act is considered a violation of the owner's rights, as it involves taking away something that belongs to someone else without their permission or consent.

In contrast, the other options touch on different scenarios that do not align with the legal definition of conversion. For instance, obtaining someone else's property legitimately pertains to lawful transactions, while using shared resources with authorization fundamentally involves permission and cooperation, which negates the element of wrongful possession that defines conversion. Lastly, exchanging property without legal approval addresses the lack of legal permissions in transactions, but does not specifically refer to taking personal property without consent, which is the core of the conversion concept.
