This question was posed to me in examination.

The query is from Pressure Measurements in section Air Data Systems, Altitude and Heading Reference of Avionics

Right answer is (c) Intrusive probe

The best explanation: All of the sensing probes, except for the flush mounted static probe, are intrusive because they disturb the local flow over the body of the aircraft. Thus they are also called intrusive probes.
