Explanation:

A compound-complex sentence has at least two independent clauses and at least one dependent clause.

1. The first option is a compound sentence (two independent clauses joined by a comma splice, no dependent clause).
2. The second option is a compound sentence (two independent clauses joined by "and", no dependent clause).
3. The third option has two independent clauses joined by "but", and a semicolon connecting related clauses, but no dependent clause.
4. The fourth option has two independent clauses: "The first is the snowstorm" and "the second is the blizzard, a violent storm that features extreme cold, strong winds, and low visibility". It also has two dependent clauses: "which brings large amounts of falling snow" (relative clause modifying "snowstorm") and "that features extreme cold, strong winds, and low visibility" (relative clause modifying "storm"), fitting the compound-complex structure.

Answer:

D. The first is the snowstorm, which brings large amounts of falling snow, and the second is the blizzard, a violent storm that features extreme cold, strong winds, and low visibility.
