Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 3.879\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(COC(=O)CCN1C(=O)/C(=C\C=C\c2ccccc2)SC1=S)Nc1ccc(Br)cc1
(b) COCCN(C(=O)COC(=O)CCS(=O)(=O)c1ccccc1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
(c) Cc1ccc(CSc2nnc(-c3ccc(S(=O)(=O)N4CCCC4)cc3)o2)cc1
Answer: a. O=C(COC(=O)CCN1C(=O)/C(=C\C=C\c2ccccc2)SC1=S)Nc1ccc(Br)cc1
