(A) hot saucesstimulate the release of endorphins in the brain, just as exercise does, andthese have a pain-relieving effect like morphine's (B) hot saucesstimulate the release of endorphins in the brain, like exercise, and they havea pain-relieving effect that is like morphine (C) hot saucesand exercise both stimulate the release of endorphins in the brain, and theyhave a pain-relieving effect like morphine (D) the releaseof endorphins in the brain is stimulated both by hot sauces and exercise, andthey have a pain-relieving effect like morphine's (E) the releaseof endorphins in the brain is stimulated by hot sauces, just as with exercise,and these have a pain-relieving effect like that of morphine
Besides addingcomplementary flavors to many foods，根据主谓一致，主语只能是hot sauces。排除D、E选项。C选项中both and的用法不对。B选项中的pain-relieving effect后用定语从句太啰嗦，并且应该用morphine's来表示morphine的效应。综合选A
