The order of intersection with the 0 dB axis in ascending order is: Type N system, Type 4 system, Type 3 system, and Type 2 system.

Type N systems are the best-behaved response systems, and their intersection with the 0 dB axis is the closest to 0 dB.

This is followed by Type 4 systems, which have an intersection with the 0 dB axis slightly further away than Type 3 systems.

Type 3 systems have an intersection with the 0 dB axis further away than Type 2 systems, but still close to 0 dB.

Lastly, Type 2 systems have the furthest intersection from 0 dB.

Hence option 1 is correct.
