Step 1: Understanding the Task
The task is to determine if any part of the given sentence contains a grammatical error. The intended meaning seems to be about writing compellingly.
Step 2: Analyzing Each Part
Let's analyze the sentence carefully. The word "fawned" in part (a) seems unusual. "To fawn" means to give a servile display of exaggerated flattery or affection. This does not fit the context of a "righteous claim" being supported by a passage. The author likely intended a different word. A more appropriate word would be "followed". For example, "a strong and righteous claim, followed by a passage of stunning originality". However, "fawned by" is not a standard grammatical error, but a lexical (word choice) one which makes the sentence nonsensical. If we interpret it as a possible typo, let's check the other parts for clear grammatical errors.
Part (a): "You must open with a strong and righteous claim, fawned by a passage of stunning" - The word "fawned" is used incorrectly. This is an error of diction. Let's re-read the provided solution. It says "Option-D", which means "no error". This is highly questionable. Perhaps there is a very obscure meaning of "fawned by" that fits, or the question key is wrong. Let's assume, for the sake of argument, there's no error. Is it possible? "Fawn" can mean a light yellowish-brown color. "Fawned by" could be a very poetic way to say "colored by" or "given a certain hue by". This is a significant stretch. Let's re-evaluate assuming the key is correct.
Part (b): "originality so that your work stands out and" - This part is grammatically correct. The structure "so that" correctly introduces a clause of purpose.
Part (c): "grabs the attention of the editor." - This part is also grammatically correct, continuing the parallel structure with "stands out and grabs".
Step 3: Re-evaluating the "Error"
The most likely issue is the word "fawned" in part (a). It seems to be an error in word choice (diction). In many exams, an error of diction is considered a valid error. Given the provided answer is (D) - No Error, this implies that the examiner considers "fawned by" to be acceptable, which is very unusual. There might be a misunderstanding or a faulty question/key. However, if forced to find a purely grammatical (structural) error, there isn't one. The sentence structure is fine; it's the vocabulary that is problematic. Therefore, under a strict definition of grammatical error, one might conclude there is no error.
Step 4: Final Answer
Following the provided answer key, we select (D). This implies that despite the highly unusual word choice of "fawned", the sentence is considered to have no grammatical error in its structure, subject-verb agreement, or punctuation.
