Answer 1

A) In the first round of the tournament, I played one of the best teams.

Answer 2

The sentence in which a comma is used correctly is:

A. In the first round of the tournament, I played one of the best teams.

A comma is placed right after a subordinate clause. A subordinate clause is not a complete sentence and they need to be accompanied by an independent clause (can stand on it's own), in order to form a complete thought.

Here is where the comma should have gone in order for options b and c to be correct:

b. In the first round of the tournament, I played one of the best teams.

c. Fortunately, I had a spare set of keys with me.
