A statement or situation that seems to be contradictory but actually presents a truth
'The sweet, smoky scent of toasted marshmallows found her nose as she licked melted chocolate from her fingertips." This is your answer as it explicitly states the sense of smell.
The answer is A i hope this helps
I believe it is A due to "The lady made detailed plans, engaged the caterer and the orchestra well in advance" isn't exactly connect well and be hard to understand so you'd put a comma between "caterer, and".
