a. forming

c. storming

d. performing

e. norming

a. forming

Explanation:

The forming–storming–norming–performing model of group development was first proposed by Bruce Tuckman  who said that these phases are all necessary and inevitable in order for the team to grow, face up to challenges, tackle problems, find solutions, plan work, and deliver results.

Forming: The team meets and learns about the opportunities and challenges, and then agrees on goals and begins to tackle the tasks. Team members come together to become oriented to the tasks as well as to one another. They meet and deliberate on defining the scope of the task, how to approach it, and similar concerns. How to move from this stage to the next, each member must relinquish the comfort of non-threatening topics and risk the possibility of conflict.

answer: marginal utility of the fourth brownie is 0.

so, marginal utility at the 4th unit will be given by

since, the values are not given here, you can simply find marginal utility at fourth unit by subtracting total utility at 3rd unit from total utility at 4th unit.
