Over the course of the eighteenth century, the average output of ironwork tripled as a result of several improvements in blowing machinery and because coal replaced charcoal as the fuel used in the smelting of iron ore.
A. Over the course of the eighteenth century, the average output of ironwork tripled as a result of several improvements in blowing machinery and because coal replaced charcoal as the fuel used in the smelting of iron ore.
B. Over the course of the eighteenth century a tripling in the average output of ironwork was due to the replacement of charcoal by coal for the fuel used in the smelting of iron ore, in addition to several improvements in blowing machinery.
C. With charcoal’s being replaced by coal as the fuel used in the smelting of iron ore and several improvements in blowing machinery, the average output of ironwork tripled over the eighteenth century.
D. The replacement of charcoal with coal for the fuel used in the smelting of iron ore and several improvements in blowing machinery, the average output of ironwork tripled over the eighteenth century.
E. Charcoal being replaced by coal as the fuel used in the smelting of iron ore, and several improvements in blowing machinery, which tripled the average output of ironwork over the course of the eighteenth century.
OA is C. While I think A is the answer. I don not think the use of "with being" in C is idiomatic.
Can anyone have some explan it for me ?
Weird answer needs to be discussed

output tripled as a result of X and because Y.
violates the parallesim.
It should of
output tripled as result of X and Y ( X and Y must be parallel)
C is also looks wrong to me.
Charcoal's being --> wrong to me (possessive)
What is the source.

Ijust found it on another GMAT BBS. Although A is not parallel, it's not grammatically wrong. But structure of C is wrong.
