Option-2 is correct.
Note the definition of utilization as follows:
Utilization of a resource = Flow rate / Capacity of the resource.
Option-1 and 3 are never possible because Flow rate = Min {Demand, Capacity} which means flow rate cannot exceed capacity. Option-4 is also not possible because when Flow rate equals capacity, it means that utilization is 1 or 100%. This is the maximum level that utilization can go. This also makes option-2 correct.
