Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.014% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: Cc1onc(NC(=O)c2ccc([N+](=O)[O-])o2)c1Br
b: CCc1ccc(CN(C)C(=O)c2cc(COc3cc(C)c(Cl)c(C)c3)on2)nc1
c: CC(C)CCNC(=O)c1ccc(Cn2c(=O)[nH]c3ccsc3c2=O)cc1
d: CC(C)CCn1c(=O)c(C(=O)N/N=C/c2cccc(F)c2)c(O)c2ccccc21
Answer: a. Cc1onc(NC(=O)c2ccc([N+](=O)[O-])o2)c1Br
