To identify the correct sentence, you need to determine the subject-verb agreement and ensure that the verb agrees with the subject in number (singular or plural). Let's break down each sentence to understand why the others are incorrect:

1. The bike on the bike rack is blue.
The subject, "the bike," is singular, and the verb, "is," agrees with the singular subject correctly.

2. The sidewalks in the courtyards has been decorated with chalk.
The subject, "the sidewalks," is plural, but the verb, "has," is singular. The correct verb to use here is "have," as in "The sidewalks in the courtyards have been decorated with chalk."

3. The surface of the parking lots were redone this summer.
The subject, "the surface," is singular, but the verb, "were," is plural. The correct verb to use here is "was," as in "The surface of the parking lots was redone this summer."

4. The cars in the parking lot belongs to the teachers.
The subject, "the cars," is plural, but the verb, "belongs," is singular. The correct verb to use here is "belong," as in "The cars in the parking lot belong to the teachers."
