Here is the item again:

Karlene drove slowly through the heavy traffic. (A) Anticipating a bag of microwave popcorn (B) and a couple of hours in front of the television (C) as her reward for a hard day at work.

You correctly realized that the period after traffic created a fragment. Anticipating a bag of microwave popcorn ... is a participle phrase, so it cannot stand alone as a complete sentence.

To fix this fragment, you chose to do this:

Karlene drove slowly through the heavy traffic, anticipating a bag of microwave popcorn and a couple of hours in front of the television as her reward for a hard day at work.

You have correctly employed Punctuation Rule 3:

Main Clause + , + Participle Phrase.

Keep up the beat!

Go to the next sentence.
