When the administrative and political models of decision making are said to be descriptive, this means: a. The model is most useful for programmed decisions b. The model defines how people actually make decisions, under less than ideal conditions c. The model is best suited for highly certain conditions d. The model defines how people should ideally make decisions

B). The model defines how people actually make decisions, under less than ideal conditions.

Explanation:

As per the question, if the administrative as well political models of decision-making are characterized as descriptive, it implies that 'the model defines how people actually make decisions when the situation is not ideal or less ideal'. The descriptive model of decision-making is associated with the ability to take decisions willfully under certain consistent rules. This theory considers the other external factors also that may affect people's decision-making under less-optimal or less-rational conditions because people not always take the decisions that 'should be or must be done' but rather according to their will. Therefore, option B is the correct answer.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
