Explanation:

Transitional words are words (there are also phrases) that are used when the author wishes to connect two different ideas. These words serve as a bridge between these ideas, making the reading pleasant and cohesive. These words also allow the reader to realize that different things (such as tenses, or different words) are connected and establish a unique meaning.

Among the options given in the question, we can see that the letter A shows an example where the use of a transitional word has been efficiently established to relate two different verb tenses.
