Answer:
The subject in the sentence is "ring'.
Step-by-step explanation:
In a sentence, the subject is the person or thing that is the main point or guiding act of the sentence. So, in the above sentence, the ring is the subject as it is the main thing that is talked about in the sentence.
The subject of any sentence can be a person, thing or even an idea that dominates and is the main cause of the whole sentence. While the noun Leslie's hand may look like the subject, it is a situational noun that supports the main subject "ring".
