Task: Answer the multiple-choice question.
Question: Which drug exhibits a -20.906\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1ccc(S(=O)(=O)NC(C)C(=O)NCCN2CCOCC2)cc1Cl
b: CCCn1nnc(NC(=O)c2ccc(F)cc2)n1
c: COc1ccc(-c2nc(CS(=O)(=O)CC(=O)NCc3ccccc3OC)c(C)o2)cc1
d: O=C1c2ccccc2C(=O)N1CCCCSc1nnc2c(Cl)cc(Cl)cn12
Answer: d. O=C1c2ccccc2C(=O)N1CCCCSc1nnc2c(Cl)cc(Cl)cn12
