Task: Answer the multiple choice question.
Query: Which drug has a -21.628\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CCOC(=O)[C@H]1[C@H]2COc3ccc(C)cc3[C@@H]2N2C(=O)CN(Cc3ccc(OC)cc3)C(=O)[C@@]12C
b: O=C(NCc1ccco1)c1ccccc1NC(=O)C1CC(=O)N(c2ccc(Cl)cc2)C1
c: COC(=O)Cn1c(C)nc2c(sc3nc(C)cc(C)c32)c1=O
Answer: b. O=C(NCc1ccco1)c1ccccc1NC(=O)C1CC(=O)N(c2ccc(Cl)cc2)C1
