Answer:
B. During lunch, the panel order food from the cafeteria and sit with their friends to take a break.
Step-by-step explanation:
This sentence uses verbs and pronouns that refer to the members of the panel as individuals rather than as a single entity. The verbs 'order' and 'sit' are in plural form, indicating that the actions are being performed by multiple individuals. Similarly, the use of 'their' also refers to the panel members as individuals. The other sentences treat 'panel' as a single entity. (Correct on Acellus.)
