Problem statement: Answer the multiple choice question.
Query: Which drug has a -21.115% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. Cc1nc(SCc2ccc([N+](=O)[O-])cc2)nc2ccccc12
b. O=C1C2C3C=CC(CC3)C2C(=O)N1c1ccc2c(c1)OCO2
c. CC(C)NS(=O)(=O)c1ccc(CCC(=O)NCc2ccncc2)cc1
d. Cc1nnc2n1-c1ccc(Br)cc1C(c1ccccc1Cl)=NC2
Answer: d. Cc1nnc2n1-c1ccc(Br)cc1C(c1ccccc1Cl)=NC2
