Task: Answer the multiple choice question.
Question: Which compound has a 5.790\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CC(=O)Nc1cc[n+](C(C)C(=O)c2ccc(Cl)cc2)cc1.[Cl-]
b COC(=O)c1c(NC(=O)/C=C/C(=O)O)sc(C)c1-c1ccc(C)c(C)c1
c CCCCn1c(N)c(N(CC(C)C)C(=O)c2ccc(-c3ccc(C(C)=O)cc3)o2)c(=O)[nH]c1=O
d O=C(Nc1ccccc1C(=O)N1CCOCC1)c1cccnc1
Answer: b. COC(=O)c1c(NC(=O)/C=C/C(=O)O)sc(C)c1-c1ccc(C)c(C)c1
