Task: Answer the multiple-choice question.
Question: Which drug has a -4.415\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] Nc1ccn(Cc2cccc(Cl)c2)n1
[b] CC1=C(C#N)C(NC(=O)c2ccc(C)cc2)(C(F)(F)F)C(=O)N1
[c] CC(C)(C)c1cc[n+](C2=C([O-])c3ccccc3C(=O)/C2=N\S(=O)(=O)c2cccs2)cc1
[d] CCCCCC(=O)N/N=C/c1ccc([N+](=O)[O-])o1
Answer: c. CC(C)(C)c1cc[n+](C2=C([O-])c3ccccc3C(=O)/C2=N\S(=O)(=O)c2cccs2)cc1
