Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.392\% human ether-à-go-go related gene (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 additional words.
Options:
[a] C=CCn1c(O)c(C(CC)=Nc2cccc(C(=O)O)c2)c(=O)[nH]c1=O
[b] CC(C)(C)C(=O)Nc1ccc(-c2nc3ccccc3c(=O)o2)cc1
[c] CC(C)(C)OC(=O)N1CCC(N(C(=O)c2ccccc2)c2ccc(F)cc2)CC1
[d] CCOP(=O)(c1ccc(N(C)C)cc1)C(O)c1ccncc1
[e] CCCc1cc(=O)[nH]c(SCc2ccc(C#N)cc2)n1
Answer: b. CC(C)(C)C(=O)Nc1ccc(-c2nc3ccccc3c(=O)o2)cc1
