Task: Answer the multiple choice question.
Query: Which drug exhibits a -3.414% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CCOC(=O)CN1C(=O)N[C@@H](CCc2ccccc2)C(C(=O)OC)=C1C
b. CC1(C)CC(NC(=O)C2CCC(=O)N(C3CC3)C2)CC(C)(C)C1
c. O=C1Nc2ccccc2C1=Nc1ccc(Cl)cc1
Answer: a. CCOC(=O)CN1C(=O)N[C@@H](CCc2ccccc2)C(C(=O)OC)=C1C
