Task: Answer the multiple-choice question.
Question: Which compound exhibits a 2.399% 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 additional words.
Options:
a: CCOC(=O)c1sc(C)c2c1NC(C)(c1ccccc1)NC2=O
b: O=C(NCc1ccc2c(c1)OCO2)c1cc(F)c(F)cc1Cl
c: COC(=O)C(CC(=O)c1ccc(Cl)cc1)c1ccc(C)cc1
d: CCn1cc([N+](=O)[O-])c(C(=O)N2N=C(c3ccc4ccccc4c3)CC2c2cc(Br)ccc2O)n1
e: Cc1c(NC(=O)C(C)n2cc([N+](=O)[O-])cn2)c(=O)n(-c2ccccc2)n1C
Answer: a. CCOC(=O)c1sc(C)c2c1NC(C)(c1ccccc1)NC2=O
