Task: Answer the multiple choice question.
Question: Which drug has a 4.468\% 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 additional words.
Options:
a: O=C(c1ccc2c(c1)OCCO2)N1CCCC(CNS(=O)(=O)c2cccs2)C1
b: COc1ccc2[nH]c3c(N4CCc5ccccc5C4)ncnc3c2c1
c: N#Cc1cc(C#N)c(N2CCN(c3cccc(Cl)n3)CC2)nc1N
d: CC1(C)N2CC3([N+](=O)[O-])CN1CC([N+](=O)[O-])(C2)C3
e: COCCN(C(=O)CSc1n[nH]c(-c2ccccc2)n1)c1c(N)n(CC(C)C)c(=O)[nH]c1=O
Answer: a. O=C(c1ccc2c(c1)OCCO2)N1CCCC(CNS(=O)(=O)c2cccs2)C1
