Answer:
b) Wrestling is considered the oldest sport that is still practiced today; in fact, competitive wrestling existed as early as 3000 BCE.
Step-by-step explanation:
The statement in option b) is not a fused sentence because it is correctly punctuated with a semicolon before the independent clause "in fact, competitive wrestling existed as early as 3000 BCE." A semicolon is used to separate two independent clauses that are closely related in meaning. The other options are fused sentences because they do not have proper punctuation to separate the independent clauses. In a fused sentence, two independent clauses are joined together without proper punctuation, which can make the sentence difficult to understand.
