Two spheres of radii `r_(1)andr_(2)` have densities `rho_(1)andrho_(2)` and sp. Heats `C_(1)andC_(2)` respectively. If they are heated to same temperature, the ratio of their rates of fall of temperature in the same surroundings will be

A

`(r_(1)rho_(1)c_(1))/(r_(2)rho_(2)c_(2))`

B

`(r_(1)rho_(2)c_(2))/(r_(2)rho_(1)c_(1))`

C

`(r_(2)rho_(1)c_(1))/(r_(1)rho_(2)c_(2))`

D

`(r_(2)rho_(2)c_(2))/(r_(1)rho_(1)c_(1))`
