Task: Answer the multiple choice question.
Query: Which drug exhibits a -38.557% 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. Cc1ccc(NC(=O)Cc2ncc(C(F)(F)F)cc2Cl)cc1Cl
b. Cc1ccc(NC(=S)NNC(=O)Nc2ccccc2)cc1
c. CC1=C(C(=O)OC2CCCC2)C(c2coc3ccccc3c2=O)C2=C(CC(C)(C)CC2=O)N1
d. S=C(Nc1ccccc1)Nc1ccc(OCc2ccc(Cl)cc2Cl)cc1
Answer: c. CC1=C(C(=O)OC2CCCC2)C(c2coc3ccccc3c2=O)C2=C(CC(C)(C)CC2=O)N1
