Answer:
"Sandy and Thomas " is an example of a compound subject. (letter A. compound)
Explanation:
<u>We can define subject as the topic of a sentence - what the sentence is about</u>. For instance, the sentence below has "I" as its subject.
- I drove all day yesterday.
<u>When a sentence has two or more subjects, we have a compound subject. This type of subject is connected by "and" or "or", and it can present commas in case there are more than two subjects. The sentence below has an example of a compound subject:</u>
<u>- Sandy and Thomas have bought their plane tickets.</u>
