I think you worded your question wrong. a molecule that is made of three oxygens is an Ozone (O3).
Opiates, come from poppy seeds; they are narcotic pain medications used to treat mild to severe pain. Ex of some medications that are opiates, are, morphine, hydrocodone, OxyContin, codeine, etc.
I would say D because Vera is illustrating going above the boundary to meet your customers needs and recommends products. It's not A because the statement would have implied the number she has served or money she made for the company. B is not correct because that has NOTHING to do with customer satisfaction, but with intelligence (education). Lastly, C is not correct because there's not enough information about how determined she wants to succeed.
Headaches and getting hungry :P
Basically it comes down to what your most likely to do. the literary definition is; the inclination toward a particular character or behaviour.
