The concepts needed to solve this question includes,

  • Parallelism
  • Pronouns
  • Modifiers
  • Grammatical Construction
  • Meaning

The appropriate answer will accurately convey the intended meaning without any grammatical or other errors when it is used in the question's underlined section. Let's examine each choice in turn to discover the perfect answer.

Option – C : Correct
This statement seems right as there are no kinds of grammar construction or other errors. Hence this is the right option.

Option – A : Incorrect
The words “discovering methane gas” followed by “Alessandro Volta” has the wrong meaning. It conveys “Alessandro Volta” as a gas name. Additionally, since time is specified, it is important that simple past should be used. The words “electric battery” must be placed immediately after “developed” followed by the modifier. Hence this option is not the correct one.

Option – B : Incorrect
Since time is specified, it is important that simple past should be used. This also has the same issue as the first option where “Alessandro Volta” is conveyed as a gas name misplaced. Hence this option is not the correct one. Also the “which will later” part is a wrong construction as it looks like it is predicting the future.

Option – D : Incorrect
The part “discovered methane gas” when put in the sentence does not has the right grammar tone. It simply is wrong as it is missing something before it. Hence this option is not the correct one.

Option – E : Incorrect
This when put in the sentence will talk about another person also. Hence this option is not the correct one.

From the explanations given above, it is clear that the third option is the right choice.
