Answer:
(A) High resistance
Step-by-step explanation:
Insulators are those materials in which there will no current passes through it.
From ohm's law we know that
from this relation it is clear that the current is inversely proportional to the resistance. It means for minimum current resistance should be very high
So in insulator we need very high resistance because we need very less or no current through insulator
So option (a) will be the correct option
