Answer: C. Suggestibility, deindividualization, and invulnerability
Explanation: The crowd, according to experts in psychology and social sciences, is a group of people gathered for some common purpose. Such a group of people is temporary, it does not have a distinct structure or hierarchy, i.e crowd behaviour is conditioned by the mutual influence of all who participate in the crowd. Since they are a group of people who are gathered for a common cause, these people are directly next to each other, they all act and influence each other, creating a psychology of the crowd or some kind of collective consciousness and behaviour. This means that the degree of individuality in the crowd decreases drastically, each individual is more susceptible to the thinking of others than usual, so individuals become more suggestive, but each individual becomes less vulnerable as the collective strength of the crowd increases resistance to each individual's vulnerability.
What manages and guides the crowd are simple and uncomplicated social norms, established on the spot by the people in the crowd. Of course, it should be borne in mind that in any crowd, the people who make up the crowd must be somewhat like-minded in order to create and channel somewhat similar emotions, all of which shape the behaviour of the masses as well as anonymity. Anonymity also contributes to the strength and behaviour of the masses, each anonymous being equally important in its influence that shapes the overall behaviour of the masses.
