Task: Answer the multiple choice question.
Question: Which drug has a 3.532\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=C1C(Cl)=C(NS(=O)(=O)c2ccc([N+](=O)[O-])cc2)C(=O)c2ccccc21
(b) C/C(=N\NC(=O)c1nn(C)cc1Br)c1cccc(NC(=O)C2CCCC2)c1
(c) Cc1nc2c(-c3ccc(F)cc3)c(C)nn2c(C)c1CCC(=O)N1CCN(c2ccccn2)CC1
(d) CCCC1=NN(C(=O)Cc2ccc([N+](=O)[O-])cc2)C(O)(C(F)(F)F)C1
Answer: b. C/C(=N\NC(=O)c1nn(C)cc1Br)c1cccc(NC(=O)C2CCCC2)c1
