A thermocouple of resistance `1.6 Omega` is connected in series with a galvanometer of `8 Omega` resistance. The thermocouple develops and e.m.f. of `10 mu V` per degree temperature difference between two junctions. When one junction is kept at `0^(@)C` and the other in a molten metal, the galvanometer reads 8 millivolt . The temperature of molten metal, when e.m.f. varies linearly with temperature difference, will be

A

`960^(@)C`

B

`1050^(@)C`

C

`1275^(@)C`

D

`1545^(@)C`
