Problem statement: Answer the multiple choice question.
Question: Which compound has a -1.694\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COC(=O)/C=C1\SC(N2CCOCC2)=C(c2ccc(OC)cc2)C1=O
[b] C=CSc1sc(Cl)c(N2CCOCC2)c1[N+](=O)[O-]
[c] NS(=O)(=O)c1ccc(C(=O)O)cc1
[d] CC1(C)Cc2c(sc(NC(=O)Nc3ccccc3)c2C(N)=O)CO1
Answer: a. COC(=O)/C=C1\SC(N2CCOCC2)=C(c2ccc(OC)cc2)C1=O
