Task: Answer the multiple choice question.
Query: Which drug exhibits a -20.364% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:

b COc1ccc(CN(C)CC(=O)NC(=O)NC2CCCCC2)cc1
c Cc1[nH]n(-c2c(Cl)cc(Cl)cc2Cl)c(=O)c1C=Nc1ccc(S(=O)(=O)N2CCOCC2)cc1
d CC(C)Cn1c(=O)c(C(=O)Nc2ccncc2)c(O)c2ccccc21
e Nc1ccn([C@@H]2O[C@H](CO)[C@@H](O)[C@@H]2O)c(=O)n1
Answer: b. COc1ccc(CN(C)CC(=O)NC(=O)NC2CCCCC2)cc1
