Task: Answer the multiple-choice question.
Query: Which compound has a 4.360\% 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 other words.
Options:
a CCO[C@H]1OC(C(=O)N2CCN(Cc3ccc4c(c3)OCO4)CC2)=C[C@@H](c2ccccc2)[C@@H]1CCCO
b O=C(NC1CCCCC1)C(c1ccc2ncccc2c1)N(Cc1ccc2c(c1)OCO2)C(=O)c1ccc2c(c1)OCCO2
c CSc1cccc(-c2nnc(NC(=O)c3cccc(N4C(=O)CCC4=O)c3)o2)c1
d CCOc1ccc(N(C(=O)CNC(=O)c2ccco2)C(C(=O)NC2CCCC2)c2cccnc2)cc1
Answer: a. CCO[C@H]1OC(C(=O)N2CCN(Cc3ccc4c(c3)OCO4)CC2)=C[C@@H](c2ccccc2)[C@@H]1CCCO
