Which sentence uses a verb that agrees with its compound subject? A. Daffodils and lilacs bloom in springtime. B. My sister and I plays tennis. C. Kevin and Kimberly walks to the park. D. Our jewelry and valuables is kept in a safe.

A. Daffodils and lilacs bloom in springtime.

The way you can tell if the verb agrees with the compound subject, is by removing the first part of the subject. Then you see if the sentence still works. "Lilacs bloom in the springtime." is the only one that works. So that is the correct answer.
