Solution

The correct option is B

Current



A vector is a quantity that has magnitude + direction + it obeys parallelogram law of vector addition.
Force is a vector.
velocity - again a vector
Current! No current is not a vector. Though it has magnitude and direction, it doesn’t obey the parallelogram law.
Pressure? Nope! It’s a scalar.
