Solution

The correct option is C Always equal to 1
As we know,

$i = \frac{A c t u a l n u m b e r o f p a r t i c l e s i n s o l u t i o n a f t e r d i s s o c i a t i o n / a s s o c i a t i o n}{N u m b e r o f f o r m u l a u n i t s i n i t i a l l y d i s s o l v e d i n s o l u t i o n}$

$i = 1$ (for non-electrolytes)

[Note - Nonelectrolytic solutes neither associates not dissociates]
