Final answer:
The duties described in the question align with Option 2, which identifies the role of a flight attendant as offering beverages and a complimentary snack to passengers during a flight.
Step-by-step explanation:
The question appears to pertain to the duties of a flight attendant, which is a role within the aviation or airline industry. The correct option that outlines the main cabin flight attendant's responsibilities would be Option 2: Offers beverages and a complimentary snack. This option accurately describes a typical service that flight attendants provide during a flight, ensuring passenger comfort by offering refreshments and snacks.
It is important to note that the other options listed are not in line with the described task of offering beverages and snacks. Therefore, the main role of the cabin crew in this context is to manage onboard service, which includes distributing food and beverages to the passengers. Flight attendants may also take part in other duties such as managing passenger requests, handling in-flight announcements, and ensuring overall flight safety, but the query specifically mentions the provision of food and drinks as the task in question.
