What is the meaning of 'onslaught'?

The term 'onslaught' refers to a violent or intense attack, often characterized by a sudden and aggressive movement against something or someone. It can imply a fierce assault or a heavy barrage, whether physically, emotionally, or verbally. The contextual use of 'onslaught' typically conveys a sense of overwhelming force or an unrelenting offensive action, which aligns starkly with option B. This understanding supports its use in scenarios involving conflict, whether in literature, news reports, or discussions surrounding military actions or significant personal challenges. The other choices, which depict calmness, peacefulness, or celebration, do not capture the aggressive connotation that 'onslaught' inherently holds.
