Final answer:
The basic tenet of Dr. Olweus's bullying prevention program is the intervention by bystanders when they witness bullying.

It is crucial for bystanders to act against bullying to prevent its negative consequences.
The correct option is D.
Step-by-step explanation:
Dr. Dan Olweus's program to prevent bullying emphasizes the importance of intervention by bystanders when they witness bullying behavior. In the context of the question, the correct answer is D) Bystanders. This is based on the understanding that bystanders are individuals who are present during an event or incident but do not take part in it.
The intervention of bystanders is a critical aspect to curb bullying, as they can disrupt the bullying behavior, provide support to the victim, and signal to the bully that their behavior is unacceptable. The bystander effect is a social psychological phenomenon where the presence of others discourages an individual from intervening in an emergency situation, due to the perceived diffusion of responsibility.
The bystander effect suggests that the greater the number of bystanders, the less likely any one person is to help. This could explain why bullying might continue to occur in the presence of others, as each bystander might assume someone else will intervene. It is important for bystanders to overcome this effect and take action when they see someone in distress, whether that's through direct intervention or by reporting the incident to an authority.
The correct option is D.
