Task: Answer the multiple-choice question.
Query: Which compound exhibits a 6.810\% 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=C1NC(=O)C(=C/C=C/c2coc3ccc(Br)cc3c2=O)C(=O)N1
[b] COc1ccc(S(=O)(=O)CCC(=O)NCCc2ccc(S(N)(=O)=O)cc2)cc1
[c] Cc1c(NC(=O)COC(=O)c2ccc(F)c(S(=O)(=O)N3CCOCC3)c2)c(=O)n(-c2ccccc2)n1C
[d] CN1CCC(Oc2ccccc2Sc2ccccc2)CC1.O=C(O)C(=O)O
Answer: a. O=C1NC(=O)C(=C/C=C/c2coc3ccc(Br)cc3c2=O)C(=O)N1
