"C".

I am not 100% with any of the choices since it could have been written in such a simple way.

The best solution would have been:
Over the course of the eighteenth century, the average output of ronwork tripled as a result of several improvements in blowing machinery and the replacement of charcoal by coal used in smelting of iron.

I think it should be A
if we break A we get
(I) the average output of ironwork tripled as a result of several improvements in blowing machinery
(II)the average output of iron work tripled because coal replaced charcoal as the fuel used in the smelting of iron ore. 
These two parts have been joined by the conjunction
and so A sounds sensible.
