John Austin, a key figure in the Analytical School of jurisprudence, provided a classic definition of ownership.
He defined ownership as a right over a determinate thing that is:
\begin{enumerate}
Indefinite in point of user.
Unrestricted in point of disposition.
Unlimited in point of duration.
The question asks which aspect is "unrestricted.
" According to Austin's precise formulation, this is the power of disposition—the owner's unrestricted right to dispose of the property, for example, by selling, gifting, or destroying it.
\textit{Note: While the provided answer key in the source image marks (C) Duration, Austin's exact terminology was "unlimited" for duration and "unrestricted" for disposition.
"Disposition" is the more precise answer for "unrestricted".
