Read the passage carefully and choose the correct answer A, B or C

Hi, my name’s Andriy. I love football, I am a great fan of AC Milan. I have also been interested in cars since I was a child. I’m crazy about driving and I also enjoy fixing cars. When I was ten, I had many toy cars. I played with them, repaired the ones my friends broke. I also used to help my dad fix his car. So, eventually I decided to become a mechanic and open up my own shop. My parents are happy with my choice, too. Because they think it’s important that I pursue a career that I like. I have a bright career now and I really enjoy it. My best friend is also interested in cars. We are planning to run the car shop together.
