Which of the following statements is correct about a scalar quantity:
(i) it remain conserved in a process
(ii) can never take negative sign
(iii) does not vary from one place to another in space
(iv) has same value for observers with different orientation of axis

(iv)

The correct answer is Option (4) → (iv)

A scalar quantity has the same value for observers with different orientation of the axes.

Scalar quantity is defined only by its magnitude. Hence, it has the same value for observers with different orientations of the axes.
