Kindly throw me light on this!
Q: A scalar quantity is one that:
a) is conserved in a process.
b) can never take negative values
c) Must be dimensionless.
d) Does not vary from one point to another in space.
e) has the same value for observers with different orientations of axes.

I feel, everything is false.
(a) is false because mass is not conserved in nuclear reactions.
(b) is false because work done ( a scalar) can be negative.
(c) is false definitely.
(d) is false because distance varies.
(e) is false because distance depends on the frame of reference chosen, right?

But the question was given as MCQ, without answers, in a text.

One of the options is correct. You are asking one question in your post and you should reexamine that one.
You mean. the last one? oh yes. Sorry. Whatever frame of reference is chosen, distance remains constant. OH yes. Thank you. So, the correct option is answer (e) .
