Final answer:
The correct answer is social pressure.
Step-by-step explanation:
The correct answer to the question is C) Social pressure.
People can be stubborn to change their mind if they made a public commitment due to social pressure. When individuals publicly commit to a certain belief or position, they may feel pressured to maintain consistency and not appear inconsistent or disloyal to their relationships.
For example, if someone publicly declares their support for a political candidate and later discovers new information or arguments that challenge their initial belief, they may resist changing their mind due to the fear of how others will perceive them and the potential strain it may put on their relationships.
