Task: Answer the multiple-choice question.
Question: Which drug has a 4.430\% 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=C(NCCC1=CCCCC1)C1CCN(S(=O)(=O)c2cnc[nH]2)CC1
b: CCOC(=O)c1c(NC(=O)CCCN2CCOCC2)sc2c1CC(C)(C)OC2
c: O=C(Nc1ccc(N2CCN(C(=O)c3ccco3)CC2)cc1)c1cccnc1Cl
d: C/C(Cn1cnc([N+](=O)[O-])n1)=N\NC(=O)c1cccnc1
e: CCOC(=O)c1c(NC(=O)CSc2n[nH]c(-c3ccco3)n2)sc(C)c1C
Answer: a. O=C(NCCC1=CCCCC1)C1CCN(S(=O)(=O)c2cnc[nH]2)CC1
