Task: Answer the multiple choice question.
Question: Which compound has a 3.222\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] CNS(=O)(=O)c1cc(NC(=O)c2cncn2-c2ccccc2)ccc1C
[b] COc1ccc(C2(c3ccc(OC)cc3)NC(=O)N(CC(=O)Nc3ccc(OC(F)F)cc3)C2=O)cc1
[c] COc1cc2c(c(OC)c1OC)-c1ccc(NC(=O)c3ccccc3)c(=O)cc1[C@@H](NC(C)=O)CC2
[d] O=C(O)CSc1nc2ccccc2[nH]1
Answer: c. COc1cc2c(c(OC)c1OC)-c1ccc(NC(=O)c3ccccc3)c(=O)cc1[C@@H](NC(C)=O)CC2
