What is the statutory speed limit (in k.p.h) of a private minibus on a freeway (unless indicated otherwise by another road sign)?

Why this is the answer

The correct answer in the official bank: 110

A private minibus on a freeway drives at the maximum speed set by law, which is 110 km/h, as long as no sign indicates a different speed. The other speeds listed are not the maximum speed the law sets for a private minibus on such a road.
