This word means the same as the given italicized word. Hence option C is correct.
Option A: 'Elegant' means 'graceful and stylish in appearance and manner'.
Option B: 'Homely' means 'simple but cosy and comfortable'.
Option D: 'Delightful' means 'very pleasant and charming'.
These words do not mean the same as the given word 'comely'.
So, options A, B and D are wrong.
