Answer: a) the other committee members are all in favor of the plan.
Step-by-step explanation:
According to the question's situation, Professor Wang does not support the below-average grade possessing students among the academic standard committee. Whereas other members of the committee want to support them.
So, Professor Wang can vote in favor if all the members of the committee decide to vote in supporting children with below average grade.This will convince Professor Wang as everyone is thinking of favoring students.
Other options are incorrect because discussing his opinion early will not necessarily change opinion of others. Private ballot voting will also lead to support the majority decision and will not include Professor Wang in that decision.Self esteem will not help in favoring students.Thus, the correct option is option(a).
