Answer:
The correct answer is option c, that is, bystander apathy.
Step-by-step explanation:
The phenomenon of bystander effect takes place when the existence of other demotivates a person from interfering in a crisis condition. The more the number of passersby, the less is the probability that any one of them will come ahead to help the individual in distress.
It is found that people more probably take any kind of action in a situation of emergency when there are few or no other bystanders standing. However, this behavioral and social undesired thing illustrated by the bystander apathy can be diminished with the help of certain explicit training and social awareness. Thus, the given case is an illustration of bystander apathy.
