Solution

The correct option is C the field is nonzero but potential is zero

potential $V = \frac{K Q}{R} = \frac{2 K q}{R} - \frac{K q}{R} - \frac{K q}{R} = 0$

potential is a scalar quantity so if $3$ charges at same distance with total charge is zero, then potential is zero

But electric field is a vector quantity, it will not be zero in this case
