Answer:
b.) nothing bad happens to you as a result
Step-by-step explanation:
Egoistic people are selfish, self-centered people who care about no one but themselves. Option a can't be the answer since an egoist person wouldn't want you cheating on them since they believe only they are capable of doing this. Option c goes against all the things an egoist believes in, and they would never feel sorry for what they did, let alone apologize. Lastly, option d can't be the answer because egoist would never tell their spouse that they're cheating because they don't think their spouse deserves to know because as mentioned before, they are selfish! The only care about their well-being so option B seems to be the most plausible here.
