Task: Answer the multiple-choice question.
Query: Which drug has a 7.638\% 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. CCN(CC(=O)NCc1ccc(F)cc1)c1ccc(S(C)(=O)=O)cc1[N+](=O)[O-]
b. CCN(CC(N)=O)S(=O)(=O)c1ccc(F)cc1
c. O=C(NC1CCCC1)c1ccc2nc(-c3ccco3)c(-c3ccco3)nc2c1
d. CC1CCCN(S(=O)(=O)c2cc3c4c(c2)CCN4C(=O)CC3)C1
e. S=c1[nH]nc(NCCc2ccccc2)s1
Answer: e. S=c1[nH]nc(NCCc2ccccc2)s1
