The correct answer is Option (1) → The person feels mental discomfort, and some aspect changes towards consistency.

Option (1) The person feels mental discomfort, and some aspect changes towards consistency. — Correct. Cognitive consistency needs the elements of an attitude system to be in the same direction. When they are not, the person feels mental discomfort, and some aspect changes in the direction of consistency.

Option (2) The person identifies with a liked source and copies the source's changed behaviour. — Incorrect. This describes Mohsin's two-step concept, where the target likes the source and then imitates the source's changed behaviour. It is change through a source.

Option (3) The attitude system takes in more member attitudes and becomes complex. — Incorrect. Simplicity or complexity refers to how many member attitudes an attitude system holds. A system is complex because it holds many attitudes.

Option (4) The central attitude loses its influence and becomes a peripheral attitude. — Incorrect. Centrality is the role of a particular attitude in the system; a central attitude influences the others more than a peripheral one. Two elements being out of line does not turn a central attitude into a peripheral one.
