Solution

The correct option is D $C o C l_{3} .3 N H_{3}$
As in octahedral complex, $[C o C l_{3} .3 N H_{3}]$ doesn't form any ion so it is non-conducting.
But other complex give atleast one ion so they are conductor.
$C o C l_{3} .4 N H_{3}$ gives two ion (one complex +one chloride).
$C o C l_{3} .5 N H_{3}$ gives three ion (one complex + two chloride).
