Which sentence is most clearly written?

The chosen sentence is the clearest because it presents the action in a straightforward manner and follows a logical sequence. It starts with the subject, Kevin’s suspicion, and then directly relates it to the sensory experience of smelling almonds, using a clear structure. This arrangement helps readers understand that Kevin's suspicion develops as he encounters a specific smell while entering the house.

In contrast, the other sentences may cause slight confusion due to their construction. The first one, while it conveys the same information, uses a less direct structure by placing the smell at the beginning, which can momentarily make the connection between the smell and Kevin's suspicion less immediate for the reader. The second option begins with "Kevin's suspicion," which is effective, but the phrasing "by the smells of almonds" could be seen as less natural compared to the flow of information given in the chosen sentence. Therefore, the clarity and logical progression in the selected sentence make it the best choice.
