Why are advantageous traits more likely to be passed onto offspring?

Why do frogs and other organism reproduce so many eggs or offspring?

• so that their babies can have friends to play with
• the more offspring the more likely the offspring will survive
• the more offspring the less likely offspring will survive 
• the more offspring the less competition
