The correct answer is letter A
Self-convenience bias is the name given to a type of cognitive bias - that is, a mental phenomenon characterized by flaws in our logical reasoning - that affects all human beings, to a lesser or greater degree. By definition, it can be said that the bias of self-convenience is a way of distorting reality in order to maintain our high self-esteem or favorable self-image.
Whenever the real world confronts you with an event that threatens your self-esteem, there is the possibility that this bias may be used to relieve discomfort.
