Task: Answer the multiple-choice question.
Question: Which compound has a -5.133% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCCOc1c(Br)cc(C(N)=O)cc1OCC
b: CCOC(=O)CN(C(=O)CNC(=O)c1ccco1)C(C(=O)NC1CCCC1)c1ccccc1OCC
c: CC(=O)Nc1ccc(NS(=O)(=O)c2ccccc2)cc1
d: OC1CCN(Cc2cn(Cc3ccccc3)nc2-c2cc3ccccc3o2)CC1
e: Cc1cccc(C(=O)N[C@H](C(=O)NCCc2ccc(Cl)cc2)C(C)C)c1
Answer: a. CCCOc1c(Br)cc(C(N)=O)cc1OCC
