Task: Answer the multiple-choice question.
Question: Which compound has a 5.586\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) CCOC(=O)C1=C(COC(=O)COc2ccc(C(C)=O)cc2)NC(=O)NC1C
b.) Cc1cccc(CCNC(=O)C2CCC(=O)N(Cc3ccc(Cl)cc3)C2)n1
c.) COc1cccc(NC(=O)CCS(=O)(=O)c2ccc3c(c2)oc(=O)n3C)c1
Answer: a. CCOC(=O)C1=C(COC(=O)COc2ccc(C(C)=O)cc2)NC(=O)NC1C
