What is necessary for maintaining clarity in modifier placement?

In terms of maintaining clarity in modifier placement, the selected choice effectively illustrates the relationship between the modifier and the subject. The phrase "Softly purring" is situated at the beginning of the sentence, making it clear that it describes the kitten. This positioning helps avoid any ambiguity about what is being modified.

By placing the modifier at the start, it sets up the reader's expectation for the subject to follow, thereby streamlining the sentence's flow and enhancing understanding. The clear connection between the action of nuzzling and the description of the kitten as "softly purring" establishes a vivid mental image without confusion regarding which noun the modifier is describing.

The other choices might introduce some ambiguity or less effective structuring, which can detract from the sentence's clarity. For example, if modifiers are misplaced or placed at various points without a logical connection to their nouns, it could lead to misunderstandings about the subject of the action or the qualities being attributed. Thus, correct placement of modifiers, as demonstrated in the chosen option, is essential for maintaining clarity and enhancing the overall comprehension of the sentence.
