Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.392\% 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, c, d, or e without using any additional words.
Options:
a: O=C(CSc1cccc2cccnc12)N/N=C/c1ccc(F)cc1
b: CC(=O)Nc1csc2ccccc12
c: Cc1ccc(OCC(O)CNC(C)c2ccccc2)cc1C.Cl
d: CCN1CCN(c2nc([N+](=O)[O-])nn2C)CC1
e: CCOc1ccc(C(C)NC(=O)c2ccccc2F)cc1
Answer: b. CC(=O)Nc1csc2ccccc12
