Task: Answer the multiple choice question.
Question: Which drug has a -0.783\% 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] Cc1nc(-c2ccc(S(=O)(=O)Nc3ccccc3C)cc2)co1
[b] CCCCn1c(N)c(N(CCOC)C(=O)c2cccc(-n3cnnn3)c2)c(=O)[nH]c1=O
[c] Cc1nc(-c2ccccc2)sc1C1(C)CC(c2ccc(C#N)cc2)=NO1
[d] O=C(/C=C/c1ccccc1)N(Cc1cccc(Cl)c1)C1CCS(=O)(=O)C1
[e] CCCCOC(=O)NCN1C(=O)C2C3C=CC(C3)C2C1=O
Answer: b. CCCCn1c(N)c(N(CCOC)C(=O)c2cccc(-n3cnnn3)c2)c(=O)[nH]c1=O
