The number of particles crossing a unit area perpendicular to X-axis in unit time is given by `n= -D (n_2 - n_1)/(x_2 - x_1)`. Where, `n_1` and `n_2` are number of particles per unit volume for the value of x meant to` x_2 and x_1` .Find the dimensions of the diffusion constant D.

B. `M^(0)L^(2)T^(-4)`
C. `M^(0)L T^(-2)`
D. `M^()L^(2)T^(-1)`
