Task: Answer the multiple choice question.
Question: Which drug exhibits a -21.558% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1cc(OC)cc(C(=O)N2CCN=C2SCc2cccnc2)c1
b: Cl.N=c1sccn1CC(=O)N(CCc1ccccc1)CCc1ccccc1
c: COc1ccc(/C(N)=N/OC(=O)Oc2ccccc2)cc1
d: O=C(CCC(=O)OC(C(=O)c1ccccc1)c1ccccc1)Nc1ccccc1
e: COc1ccc(C(=O)NCC(=O)OCc2ccc(Br)cc2)cc1
Answer: a. COc1cc(OC)cc(C(=O)N2CCN=C2SCc2cccnc2)c1
