Task: Answer the multiple-choice question.
Query: Which compound has a 15.743\% 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 other words.
Options:
a CCC(C)(C)c1ccc(O)cc1
b CC1=C(n2nnc3ccccc32)C(c2ccccc2)C(C#N)=C(N)O1
c O=C(NCCc1ccc(Cl)cc1)c1nnc(Cc2ccc(Cl)cc2)o1
d O=C(NCc1cn2ccsc2n1)Nc1ccc(Cl)cc1
e CC(/C=C/c1ccccc1)=N\NC(=O)c1cc(C)[nH]n1
Answer: c. O=C(NCCc1ccc(Cl)cc1)c1nnc(Cc2ccc(Cl)cc2)o1
