Task: Answer the multiple choice question.
Question: Which drug exhibits a -6.078% 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. COC(=O)c1ccc(CSc2nnnn2-c2ccccc2)o1
b. COc1ccc(OCC(O)CN2CC(C)OC(C)C2)cc1.Cl
c. Cc1nc(CNS(=O)(=O)c2ccc(Br)cc2)cs1
d. O=C(CSc1nnc(CNC(=O)c2ccco2)o1)Nc1ccccc1F
Answer: a. COC(=O)c1ccc(CSc2nnnn2-c2ccccc2)o1
