Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.261\% 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) O=C1NC(=O)C(Nc2cccc3ccccc23)S1
b) CN(C)C(=O)CSc1ccccc1C(=O)OCC(=O)NC1CC1
c) O=C(CNC(=O)C(c1ccccc1)c1ccccc1)OCc1ccccc1
d) O=C(NCCCN1CCN(c2ccc(F)cc2)CC1)Nc1ccc([N+](=O)[O-])cc1
e) N#Cc1cn(CCOC(=O)c2cccc(C(F)(F)F)c2)c(=O)[nH]c1=O
Answer: b. CN(C)C(=O)CSc1ccccc1C(=O)OCC(=O)NC1CC1
