'Doughty' means brave, valiant, intrepid, or resolute. It describes someone who shows courage and determination, especially in difficult situations. Option D 'all of the above' is correct because all three options - A 'gutsy' (brave), B 'gallant' (brave in a dashing way), and C 'intrepid' (fearless) - are valid synonyms of doughty. This is an older word that is still used in literary contexts to describe courageous character.
