Your answer is correct.

Im sorry, my names Heather-Alondra.

I thought I had but it full.

Yes, A is the correct answer. To combine the two sentences into a complex sentence with a dependent adjectival clause, we use the relative pronoun "who" to join the two ideas together. The resulting sentence is: "The boy who wore a green coat carried his sister home." This sentence conveys that the boy who was wearing a green coat also carried his sister home.
