What is property of porosity and temperature change in insulating mate

1.	What is property of porosity and temperature change in insulating materials?(a) Less, less affected(b) Less, highly affected(c) High, highly affected(d) High, less affectedI got this question in an interview for job.I'd like to ask this question from Insulating Materials topic in chapter Electrical Engineering Materials of Design of Electrical Machines
Answer» The correct option is (a) Less, less affected For explanation I would say: The insulating materials should have less POROSITY as it should not lose the internal properties due to HOLES. The MATERIAL should also be less affected by TEMPERATURE change in ORDER to preserve its properties.
