How can the impact of a gale be described in relation to the south coast?

The correct choice highlights the significant influence of the gale on the south coast, emphasizing that it experienced the most severe impacts. The phrase "bore the brunt" conveys that the south coast was directly and intensely affected, indicating that it faced the strongest winds and possible damage associated with the gale. This choice suggests that the south coast experienced extreme conditions rather than merely undergoing mild effects or being spared from harm, which informs the reader of the gale's severity and the coastal area's vulnerable position.

In contrast, other options either understate the impact, suggest a lack of effects, or imply a protective outcome, thus not accurately reflecting the seriousness of the situation as acknowledged in the correct answer choice.
