D) Many animals engage in pandiculation: stretching and yawning behavior.​

Answer 1

A) Common examples of synchronization are: tickling, laughing, and wrestling.

Step-by-step explanation:

A colon is a punctuation mark that is used to list, announce, or introduce or separate independent clauses in a sentence. Moreover, it is also used to connect a list to the other parts of the sentence if they are related.

In the given sentences, the correct usage of the colon is seen in sentence A. This is because the sentence contains a list of examples of synchronization. Other sentences are continuous sentences, with either just one independent clause. They need no use of the colon.

Thus, the correct answer is option A.
