Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.815\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=S(=O)(c1cccc(Cl)c1)N1CCSc2ccccc21
b: CNC(=O)c1ccccc1NC(=O)C1CC(=O)N(c2ccc(OC)cc2)C1
c: Cc1cccnc1NC(=O)Cn1c(=O)oc2ccccc21
d: O=C(NCCc1ccc(Cl)cc1)c1cc(S(=O)(=O)N2CCCCC2)c[nH]1
e: CN1CCc2nc(SCc3ccccc3Br)c(C#N)cc2C1
Answer: e. CN1CCc2nc(SCc3ccccc3Br)c(C#N)cc2C1
