Task: Answer the multiple-choice question.
Query: Which drug has a 16.358\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] O=S(=O)(c1ccc2nnn(O)c2c1)N1CCCCC1
[b] CCOC(=O)c1sc(=S)n(-c2ccccc2)c1NC(C)=O
[c] C/C(CC(=O)N(C(C)C)C(C)C)=N\NC(=O)COc1ccc(Cl)cc1Cl
[d] CCCCN(C)CCn1c(=S)[nH]c2ccc(N3CCOCC3)cc2c1=O
[e] C/C(=N\NC(=O)c1cccc(Br)c1)c1cccnc1
Answer: b. CCOC(=O)c1sc(=S)n(-c2ccccc2)c1NC(C)=O
