NOTE -- "in treating adultery" is wrong idiom.
- The correct way to say this would be "something IS treated as an offence" or "the court IS treating this as a murder" or "The court IS treating adultery as an offence".
A,B & D is clearly wrong, now between C & E -
- In C, "not only is X but also noun is Y" breaks parallelism.
- In E, the first part of the sentence correctly modifies "Section 497" and no parallelism issues.
