Task: Answer the multiple choice question.
Question: Which compound has a 1.838\% 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 additional words.
Options:
a: O=C1SCCC1NS(=O)(=O)c1ccc([N+](=O)[O-])cc1
b: COC(=O)c1ccc(NC(=O)CCN2CCCCC2)cc1.Cl
c: CCOCCCNC(=O)Cc1ccc(Br)cc1
d: O=C(NCCN1CCOCC1)Nc1ccc(Cl)cc1Cl
e: Cc1c(O)c(CN2CCCCC2)cc2c3c(c(=O)oc12)CCC3
Answer: a. O=C1SCCC1NS(=O)(=O)c1ccc([N+](=O)[O-])cc1
