Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 16.668\% 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 other words.
Options:
a CSc1ccccc1NC(=O)N1CCCC(C(=O)c2ccc3c(c2)OCO3)C1
b CCc1nn(CC(=O)NCc2ccccc2Cl)c(=O)c2cccn12
c O=C(Nc1ccc(Br)cc1)/C(=C/c1cccc([N+](=O)[O-])c1)NC(=O)C1CCCCC1
d O=C(NNC(=O)C1CC(c2cccnc2)=NO1)Nc1ccccc1F
e O=C(CSc1nccc(=O)[nH]1)NC1CCCC1
Answer: e. O=C(CSc1nccc(=O)[nH]1)NC1CCCC1
