The correct answer is A. well-bred.
A genteel lady is one who is well-bred, refined, and polite. She is someone who is considered to be of high social class and who behaves in a way that is considered to be proper and respectable.
The other options are not as accurate descriptions of a genteel lady. A delicate lady is one who is fragile and easily injured. An attractive lady is one who is pleasing to look at. A beautiful lady is one who is very attractive.
While a genteel lady may be all of these things, she is not defined by them. She is defined by her good breeding, her refinement, and her politeness.
