Hi chetan2u,
How do we know that it was "isolation of Insulin" and not "insulin" which was a significant medical breakthrough since, Insulin is also a medical term.
also in B, antecedent of "It" is not clear. Can we say for sure that 'it' is referring to real story?

Perhaps the most significant medical breakthrough of the twenties, the real story behind the isolation of insulin was not revealed for over fifty years .

A)Perhaps the most significant medical breakthrough of the twenties, the real story behind the isolation of insulin was not revealed for over fifty years.
The phrase Perhaps the most significant medical breakthrough of the twenties must modify isolation of insulin. It makes no sense for this phrase to modify the real story.
B)The real story behind the isolation of insulin was not revealed for over fifty years, even though it was perhaps the most significant medical breakthrough of the twenties.
This sentence can be rephrased as even though it was perhaps the most significant medical breakthrough of the twenties,The real story behind the isolation of insulin was not revealed for over fifty years. Here again there is modifier error as in choice A. The most significant medical breakthrough was isolation of insulin and the the real story.
C)Although the isolation of insulin was perhaps the most significant medical breakthrough of the twenties, the real story behind it was not revealed for over fifty years.
Correct
D)The real story behind the isolation of insulin was not revealed for over fifty years, although insulin was perhaps the most significant medical breakthrough of the twenties.
Modifier error. Insulin was not the most significant medical breakthrough but the isolation was. We can decide whether it was insulin or isolation of insulin from Choice A which usually provides the intended meaning of the author. So, as per choice A it must be isolation that should be modified and insulin.
E)Although insulin was perhaps the most significant medical breakthrough of the twenties, its isolation was not revealed for over fifty years.
Same error as D change in intended meaning.
