Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.622\% 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, b, or c without using any additional words.
Options:
(a) O=c1c2cc(F)ccc2sn1-c1ccccc1
(b) O=C(CNS(=O)(=O)c1ccc(C(=O)N2CCOCC2)cc1)N1CCOCC1
(c) CC1(CCl)N([O-])C2=C(CCCC2)[N+]1=O
Answer: c. CC1(CCl)N([O-])C2=C(CCCC2)[N+]1=O
