Task: Answer the multiple choice question.
Question: Which compound has a 20.384\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CC1=CC(C)(C)N2C(=O)C3(NCCc4c3[nH]c3ccccc43)c3cc(C)cc1c32
b) O=S(=O)(c1ccc(Cl)cc1)N1CCC2(CC1)OCCO2
c) O=C(Nc1nnc(C2=COCCO2)o1)c1cccc([N+](=O)[O-])c1
Answer: a. CC1=CC(C)(C)N2C(=O)C3(NCCc4c3[nH]c3ccccc43)c3cc(C)cc1c32
