Fill in the blank with appropriate option.She has a driving license. She _ drive the car on the motorway.

Explanation

The correct answer is 'can' because it indicates present ability or capability. Since she possesses a driving license, it logically follows that she has the ability to drive on the motorway. 'Must' implies necessity rather than ability, 'may' suggests permission rather than ability, and 'could' typically refers to past ability or hypothetical scenarios, none of which appropriately fit the context of this sentence.
