Correct Answer: knackered

Solution : The second option is correct.

Knackered is a slang term primarily used in British English and means extremely tired or exhausted. In the context of someone who has been travelling for 2 days straight, knackered specifically refers to a state of extreme fatigue or exhaustion, which fits the situation better than the others.

The meanings of other words are as follows:

• Worried : This refers to feeling anxious, troubled, or concerned about something.
• Adjure : This means to earnestly request or urge someone to do something.
• Deferred : This means to be delayed or postponed to a later time; to put off an action or decision to a future date or time.

Therefore, the complete sentence is: After travelling for 2 days straight, Reema was too knackered.
