$A$. hold the sheet there if it is magnetic.
$B$. hold the sheet there if it is non-magnetic.
$C$. move the sheet away from the pole with uniform velocity if it is conducting.
$D$. move the sheet away from the pole with uniform velocity if it is both, non-conducting and non-polar.
Choose the correct statement($s$) from the options given below:

$(a)$ Velocity of light in the second medium is $1.73$ times the velocity of light in the $I$ medium
$(b)$ Velocity of light in the $I$ medium is $1.73$ times the velocity in the $II$ medium
$(c)$ The critical angle for the two media is given by $\sin \,{i_c}\, = \,\frac{1}{{\sqrt 3 }}$
$(d)$ $\sin \,{i_c}\, = \,\frac{1}{2}$
