Which of the following words is synonymous with 'quarrelsome'?

The word 'quarrelsome' describes someone who is inclined to argue or engage in disputes, often exhibiting a contentious or combative nature. 'Hostile' aligns well with this definition because it implies a disposition that is unfriendly, antagonistic, or confrontational, which fits the essence of being quarrelsome. Individuals who are quarrelsome often display hostility towards others, making 'hostile' a suitable synonym.

In contrast, options like 'amicable' and 'friendly' suggest a sense of kindness and willingness to cooperate or get along with others, which is directly opposite to being quarrelsome. Likewise, 'composed' indicates a calm and self-control demeanor, further diverging from the aggressive nature associated with quarrelsomeness. Therefore, 'hostile' is the term that best captures the antagonistic quality of being quarrelsome.
