Task: Answer the multiple choice question.
Question: Which drug exhibits a -2.201\% 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 additional words.
Options:
a. O=C(CSc1nc2ccccc2o1)N1CCN(C(=O)c2ccco2)CC1
b. CCOC(=O)N1CCN(C(=O)C2CCN(S(=O)(=O)c3cc(Cl)ccc3Cl)CC2)CC1
c. CCN(C(=O)c1cnc(OC)cc1C(F)(F)F)c1ccc(Cl)cc1Cl
d. CC1(CCc2ccccc2)NC(=O)N(Cc2nnc(-c3ccccc3Br)o2)C1=O
Answer: d. CC1(CCc2ccccc2)NC(=O)N(Cc2nnc(-c3ccccc3Br)o2)C1=O
