As shown in the figure, a point charge $Q$ is placed at the centre of conducting spherical shell of inner radius a and outer radius $b$. The electric field due to charge $Q$ in three different regions I, II and III is given by: $( I : r < a , II : a < r < b , III : r > b )$

A

$E _{ I }=0, E _{ II }=0, E _{ III } \neq 0$

B

$E _{ I } \neq 0, E _{ II }=0, E _{ III } \neq 0$

C

$E _{ I } \neq 0, E _{ II }=0, E _{ III }=0$

D

$E _{ I }=0, E _{ II }=0, E _{ III }=0$
