Answer:B) inattention to alternatives
Step-by-step explanation:
inattention to alternative: this means a person who is in a relationship with someone else doesn't pay attention to other people that she or he may also potentially date. This means the person has no interest in looking for any other partner apart from the one she or he has in way that they may not even be aware of a person who makes an advance towards them. This kind of person doesn't even fantasize about what they would be doing in an alternative relationship.
This is the case with Betty , she couldn't even notice that her boss was interested in her eventhough other people could notice which means she was paying no attention to anyone else apart from her husband.
This is crucial in saving most marriages because it means someone is content with their partners and they are not looking for anyone else , this means the person will be loyal to the relationship always.
