You didn't post any passage...
Personally , I think A is the best. It has facts (less expensive, close) and it doesn’t have too much opinion. Rather than “everybody likes animals” or “my favorite animals live in the reptile house” it shows that it’s practical and fun!
Should, must, don’t have to, need to
Hope this helped!
