If the conductance of a conductor (G) is `(I^(2)t)/(W)` where I is current t is time and w is work done then the unit of conductance expressed in terms of fundamental units is `"________"`
A. `(A^(2)s^(3))/(kg^(2)m) `
B. `(A^(2)s^(3))/(kg^(-2)m)`
C. `(A^(2)s^(3))/(kgm^(2))`
D. `(A^(2)s^(3))/(kg^(2)m^(-2))`
