Suppose a quantity,-v can be dimensionally represented in terms of M, L and T, that is, [x] = Ma LbTc. The quantity mass
(a) can always be dimensionally represented in terms of L, T and x,
(b) can never be dimensoinally represented in terms of L, T and x,
(c) may be represented in terms of L, T and x if a = 0
(d) may be represented in terms of L, T and x if a ≠ 0.
