Which transformation conveys that the weather prevented us from going out?

The transformation that conveys that the weather prevented going out is particularly clear in the selected option. The phrase "prevented us from going out" explicitly indicates a blockage or barrier caused by the weather, which aligns perfectly with the intended meaning of the original statement.

Using the term "prevented" directly connects the cause (bad weather) with the effect (not going out), making the relationship straightforward and unmistakable. This communication of causality is crucial in situations where understanding the impact of one factor on another is necessary.

Other options, while also pointing to adverse weather conditions, either use different phrasing or imply a result without the same level of direct causation. For instance, some alternatives focus on severity or difficulty but do not use the explicit word "prevented," which is central to conveying the original intent effectively. Thus, the clarity and directness of the correct choice ensure that the intended meaning regarding the influence of weather on outdoor plans is communicated without ambiguity.
