The magnitude of any physical quantity

Statement-I : If the initial and final positions coincide, the displacement is a null vector. Statement-II : A physical quantity can not be called a vector, if its magnitude is zero.

Assertion : If the initial and final positions coincide, the displacement is a null vector. Reason : A physical quantity cannot be called a vector, if its magnitude is zero.

Assertion: If the initial and final positions coincide, the displacement is a null vector. Reason: A physical quantity can not be called a vector, if its magnitude is zero.

Can a physical quantity having both magnitude and direction be a vector?

Assertion: A physical quantity cannot be called as a vector if its magnitude is zero. Reason: A vector has both, magnitude and direction.

Statement-I : A physical quantity can be regarded as a vector, if magnitude as well as direction is associated with it. Statement-II : A physical quantity can be regarded as a scalar quantity, if it is associated with magnitude only.
