The correct sentence is: "The bike on the bike rack is blue."

To determine the correct sentence, we need to identify the subject-verb agreement and noun-verb agreement. Let's analyze each sentence:

1) "The sidewalks in the courtyards has been decorated with chalk."
The subject "sidewalks" is plural, so it requires a plural verb. However, the verb "has" is singular, which makes this sentence incorrect. The correct version would be: "The sidewalks in the courtyards have been decorated with chalk."

2) "The surface of the parking lots were redone this summer."
Here, the subject "surface" is singular, so it requires a singular verb. However, the verb "were" is plural, making this sentence incorrect. The correct version would be: "The surface of the parking lots was redone this summer."

3) "The cars in the parking lot belongs to the teachers."
In this sentence, the subject "cars" is plural, so it requires a plural verb. Also, the verb "belongs" should be "belong" to match the plural subject. Therefore, the correct version would be: "The cars in the parking lot belong to the teachers."

4) "The bike on the bike rack is blue."
This sentence correctly matches the subject "bike" with the singular verb "is." Therefore, this sentence is correct.
