Answer:
B The appointed day arrived; the king and his court were in their places.
Explanation:
A semicolon is used to join two independent clauses. These independent clauses may even function as complete sentences. The independent clauses must be closely related in thought. An independent clause refers to any group of words containing both a subject and a predicate.
Hence, looking at the sentence, The appointed day arrived; the king and his court were in their places.
"The appointed day arrived" as well as "the king and his court were in their places" are both independent clauses that are closely related in thought.
Hence, the correct use of the semicolon is in this sentence.
