Task: Answer the multiple-choice question.
Query: Which drug has a 6.698\% 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 other words.
Options:
a: CC(C)COn1c(=S)[nH]c2ccccc2c1=O
b: O=C(Cn1cc(C(F)(F)F)cc(Cl)c1=O)NCCc1ccc(Cl)cc1Cl
c: COCCOC(=O)c1c(C)oc2ccc(OCC=C(C)C)cc12
d: CCOc1ccccc1NC(=O)CN(c1ccc(OC)cc1OC)S(=O)(=O)c1ccccc1[N+](=O)[O-]
e: COc1ccc(NC(=O)CCCNC(=O)Cn2cnc3sc(C)c(C)c3c2=O)cc1Cl
Answer: b. O=C(Cn1cc(C(F)(F)F)cc(Cl)c1=O)NCCc1ccc(Cl)cc1Cl
