The inspection period in Arizona residential contracts is typically:

A is incorrect as 3 days is too brief for thorough property inspections. This timeframe might apply to other contingencies in some states but not to the standard inspection period in Arizona residential contracts.

C is incorrect as 30 days exceeds the standard inspection period in Arizona. While parties could negotiate a longer period, the AAR contract defaults to 10 days, making 30 days non-standard.

D is incorrect because Arizona residential contracts do have a standard inspection period of 10 days. This standardized provision helps ensure consistency and predictability in real estate transactions across the state.
