Task: Answer the multiple choice question.
Question: Which compound exhibits a -10.443% 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 additional words.
Options:
(a) COc1ccccc1N1CCN(S(=O)(=O)CCNC(=O)C2CC(=O)N(c3ccccc3)C2)CC1
(b) O=C(N/N=C/C(Br)=C\c1ccccc1)c1ccco1
(c) O=C(Cc1ccccc1)Nc1ccc(C(=O)O)cc1
(d) Cn1c(=O)c2c(-c3ccccc3)n(-n3cnnc3)cc2n(C)c1=O
Answer: b. O=C(N/N=C/C(Br)=C\c1ccccc1)c1ccco1
