The minimum limits in Alabama for automobile liability are

These limits indicate $20,000 for bodily injury per person, $40,000 for total bodily injury per accident, and $20,000 for property damage. While these figures represent a form of liability insurance, they fall below the minimum required amounts in Alabama, thus rendering this option incorrect.

This option suggests $20,000 for bodily injury per person, $50,000 for total bodily injury per accident, and $20,000 for property damage. Although the total bodily injury limit meets the state's requirement, the bodily injury per person and property damage limits are insufficient, making this choice invalid as well.

Here, the limits are set at $30,000 for bodily injury per person, $60,000 for total bodily injury per accident, and $30,000 for property damage. While these amounts exceed the minimum requirements, they do not align with Alabama's mandated coverage levels, thus rendering this option incorrect.
