The three levels of prison classification include: Minimum, low, and maximum Low, medium, and maximum Pre-lease, low, and medium Restricted, medium and maximum

The correct answer is: Low, medium, and maximum.<br /><br />Prisons are typically classified into three levels based on the security measures and restrictions in place:<br /><br />1. Low-security level: These prisons have fewer security measures and restrictions compared to medium and maximum-security prisons. Inmates in low-security prisons are considered less dangerous and are often serving shorter sentences.<br /><br />2. Medium-security level: These prisons have more security measures and restrictions compared to low-security prisons. Inmates in medium-security prisons are considered more dangerous and are often serving longer sentences.<br /><br />3. Maximum-security level: These prisons have the highest level of security measures and restrictions. Inmates in maximum-security prisons are considered the most dangerous and are often serving the longest sentences.<br /><br />The other options provided are not accurate classifications of prison levels.
