The correct answer is:

3) are warm blooded and give live birth

Mammals are homothermic (or endothermic), which means they maintain a constant body temperature (warm-blooded), and they are viviparous, which means they give birth to live young rather than laying eggs (with some exceptions, like monotremes, which are egg-laying mammals).
