Final answer:
The correct answer is d. Representative, as the corporate president acts in an official capacity to symbolize and speak for the company at events like an inauguration.
Step-by-step explanation:
The president of NuBuild Corp., acting as the corporation's representative, attended the inauguration of a customer's new office complex.
When a company's president attends an event like an inauguration, they generally do so in their official capacity to represent their company. This involves interacting with clients, other businesses, and potential partners to ensure that the corporation's interests and image are maintained and promoted.
While a liaison may facilitate communication between organizations and an ambassador may act as a ceremonial figure representing a country or a cause, a representative, in a business context, is someone who stands in or speaks for the company officially. Legislative liaison and lobbyist terms, though related to roles that may interact with government or external entities, are specific to contexts involving law-making or political endeavors rather than general corporate representation at events.
