Which three of the above would be signs of asphyxiation by strangulation

Hi, I'm looking for help understanding which three of the above would be signs of asphyxiation by strangulation. I've read about the potential symptoms of asphyxiation, but I'm not sure which are specific to strangulation. Can anyone help me understand the differences in symptoms for asphyxiation and strangulation? I'd really appreciate any advice from other forum users.
