Consider the systems given in column-I. The dominant methods for heat transfer is given in column-II. Match the proper condition:

Column-I	Column-II
(a)  Shining metal ball (system) in an evacuated isothermal chamber in steady state	(p) Radiation
(b)  Grey body (system) in evacuated isothermal chamber in steady state	(q) Conduction
(c)  Thermally insulated rod (system) is in contact with reservoirs in steady state in an evacuated chamber	(r) Convection
(d)  Water (system) being supplied heat in a thermally insulated chamber	(s) Conduction and convection

• A

  a$\to$p, b$\to$p, c$\to$q, $\mathrm{d}\to \mathrm{s}$

• B

  a$\to$s, b$\to$q, c$\to$p,$\mathrm{d}\to r$

• C

  a$\to$q, b$\to$q, c$\to$p,$\mathrm{d}\to \mathrm{s}$

• D

  a$\to$p, b$\to$q, c$\to$s,$\mathrm{d}\to r$
