Task: Answer the multiple choice question.
Query: Which drug has a 1.740\% 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 other words.
Options:
(a) O=C(Cc1cccc2ccccc12)N/N=C/c1ccc(O)c([N+](=O)[O-])c1
(b) CCOC(=O)c1c(C)n(C)c2ccc(OCC(O)CN3CCCCCC3)cc12.Cl
(c) Cc1ccc(-c2nnc(NC3CCCC3)s2)cc1
Answer: b. CCOC(=O)c1c(C)n(C)c2ccc(OCC(O)CN3CCCCCC3)cc12.Cl
