Task: Answer the multiple choice question.
Question: Which compound has a 12.858\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] CN(C1CCS(=O)(=O)C1)S(=O)(=O)c1ccc(N2CCCC2=O)cc1
[b] O=C(NNc1ccccn1)c1ccc(Cl)nc1
[c] Cc1ccc(C)c(C(C)NC(=O)c2ccccc2Br)c1
[d] CCOC(=O)C1=C(C)N=C2SC(C(=O)OC)=CC(=O)N2C1c1ccc(F)cc1
[e] N#C/C(=C\c1c[nH]c2ccccc12)C(N)=O
Answer: d. CCOC(=O)C1=C(C)N=C2SC(C(=O)OC)=CC(=O)N2C1c1ccc(F)cc1
