Answer:
The sentence that is punctuated correctly is the following one: Blue streak was determined to win; however, another worse was hot on his tail.
Explanation:
In the sentence above, there is a conjunctive adverb: however. When you have a conjunctive adverb linking two independent clauses, you should use a semicolon. As you can see, the conjunctive adverb in the sentence above is connecting the two independent clauses in the sentence. Moreover, there is comma after however because it is in initial position in the sentence. For all these reasons, the sentence is punctuated correctly.
