Explanation:

In the sentence, Shelby counted apples in each basket and used "addition" to find the total. The first definition ("the act of adding numbers together") fits because finding a total from individual counts of apples (which can be represented as numbers) involves adding those numbers. The second definition refers to something added onto another, which doesn't relate to finding a total here.
