A
have DNA
B
release energy
C
reproduce
D
have protein
Explanation: 

Detailed explanation-1: -Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

Detailed explanation-2: -Viruses are too small and simple to collect or use their own energy – they just steal it from the cells they infect. Viruses only need energy when they make copies of themselves, and they don’t need any energy at all when they are outside of a cell.

Detailed explanation-3: -Finally, a virus isn’t considered living because it doesn’t need to consume energy to survive, nor is it able to regulate its own temperature.

Detailed explanation-4: -The ability to reproduce is a living characteristic that is observed in viruses. Viruses use the cellular components of the host cell which it infects to reproduce. A genetic material is present inside the viruses like other living organisms.
