Task: Answer the multiple choice question.
Query: Which compound exhibits a 3.370% 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 other words.
Options:
a. C=CCn1c(SCc2cc(=O)n3ccsc3n2)nc2scc(C3CC3)c2c1=O
b. COc1ccc(NC(=O)c2nc[nH]c2C(=O)N[C@@H](C)C(=O)OC(C)(C)C)cc1
c. O=C(Nc1ccccn1)c1ccc2c(c1)S(=O)(=O)c1ccccc1C2=O
d. COc1ccc(C(=O)N2CCNC(=O)C2CC(=O)Nc2cc(Cl)ccc2OC)cc1
Answer: b. COc1ccc(NC(=O)c2nc[nH]c2C(=O)N[C@@H](C)C(=O)OC(C)(C)C)cc1
