A member of the executive board may not:

The correct answer emphasizes the ethical considerations and potential conflicts of interest that arise when board members are involved in providing goods or services to the association they oversee. When an executive board member also stands to benefit from a contract with the association—through providing goods or services—it can create an appearance of impropriety. This situation can lead to decisions that favor the individual over the best interests of the association and its members.

In most community associations, there are policies and regulations aimed at maintaining fairness and transparency in operations. Allowing a board member to provide services or goods directly could undermine these principles because it may influence their decision-making process regarding contracts and expenditures. To prevent conflicts of interest, it's standard for community governance to prohibit board members from conducting business with the association.

The other choices, while potentially relevant in different contexts, do not address conflicts of interest directly. Board members typically have the right to vote on contracts or bids, are usually required to pay assessments just like any other member, and can be fined for violations of governing documents if those apply to their actions as members of the association. Thus, choice C stands out as the correct response regarding the limitations placed on board members to maintain integrity in their governance role.
