Task: Answer the multiple choice question.
Query: Which compound exhibits a -20.393\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. COCCNC(=O)Cn1ccc2cc(S(=O)(=O)N3CCCCC3)ccc21
b. CN(C)CCO/N=C(\c1ccc(Br)cc1)c1cccnc1.O=C(O)C(=O)O
c. O=C(Nc1cccc(S(=O)(=O)Nc2ccc(Cl)cc2)c1)c1ccccn1.O=C(O)C(=O)O
Answer: b. CN(C)CCO/N=C(\c1ccc(Br)cc1)c1cccnc1.O=C(O)C(=O)O
