Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.042\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) O=C(NCCCN1CCCC1)C1CCN(C(=O)c2cc3sccc3n2Cc2ccc(F)cc2)CC1
(b) CCc1ccc(CN2CCN(C(=O)c3ccco3)CC2)cc1.O=C(O)C(=O)O
Answer: a. O=C(NCCCN1CCCC1)C1CCN(C(=O)c2cc3sccc3n2Cc2ccc(F)cc2)CC1
