Which of the following best describes the term 'inaugurate'?

The term 'inaugurate' specifically refers to the formal process of bringing someone into office, particularly in a political or ceremonial context. This involves an official ceremony, such as the swearing-in of a president or other elected official, marking the beginning of their term in office. The action signifies a transition of power or the commencement of a new leadership role, which is a significant event in governance and public affairs.

The other options do not capture the essence of what 'inaugurate' means. Making someone angry does not relate to the formalities of office or ceremony. Initiating a casual meeting implies a much less formal situation and does not denote the seriousness associated with an inauguration. Delaying an event also stands in contrast to the concept of an inauguration, which is about starting something rather than postponing it. Therefore, the choice that best aligns with the definition of 'inaugurate' is the one that describes the formal induction of an individual into a position of authority.
