Explanation

Creating a filter: There are a few flags in this sentence. By "flags," we mean grammatical elements that may not be present in a sentence, but which we should immediately check when we see them. "Not only... but also..." is a two-part expression. For all two-part expressions, we should check that the wording is parallel, in a) the sequence of the words and b) the conjugation of the two things in the construction. Here, the verbs are not parallel: "Sharing" should be "share" to match "provide." The sentence could correctly read, "not only provide... but also share." We'll use that as our filter and go to the answer choices.  

Applying the filter: our filter leaves us with only two choices, (C) and (E).

Finding objective defects: Choice (E) has other problems. It includes the word "being" unnecessarily at the beginning of the sentence. Gerunds of the verb "to be," such as "being," are often in error, especially when they can be omitted from the sentence. Also, where it says "launching" at the end of the phrase, it changes the meaning of the sentence. The imaginary author of this sentence is trying to talk about sharing a specific passion, a "passion to launch" something. We briefly confirm that the other answer choices are in error. The correct answer is (C).
