Explanation:

A sentence contains a compound subject if the subject (agent of the action) includes two or more words that could act as independent subjects. In the case of combining two or more sentences, a compound subject is the result of each sentence having a different subject.

This occurs in the sentences presented because the verb and complement "are majestic animals" are the same in both sentences while the subject is different which leads to two subjects or a compound subject in the sentence "Lions and tigers are majestic animals" as both "lions" and "tigers" are simple subjects.
