of one minute, the insulation resistance of medium and low voltage
installations shall be at least :
1
kilo ohm
1 mega ohm
100 mega ohm

At
pressure of 500V applied between each live conductor and earth for a period of
one minute, the insulation resistance of medium and low voltage installation
shall be at least 1 mega ohm.
Hence,
the correct option is (B).
