Answer: D, A, C

Explanation: I know this because Mammals sexually reproduce. The male sperm fertilizes the females egg. AKA internal fertilization. Endothermic is when an organism requires heat to survive. Yes, mammals need heat to live. that is why we are warm blooded. Mammals have a very complex nervous system otherwise we would not be able to feel anything.
