Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.797\% 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, or d without using any other words.
Options:
[a] COc1ccc(NC(=O)CSC(C)c2nc3ccccc3c(=O)[nH]2)cc1
[b] CCOc1ccc(NC(=O)C2CCCN(S(=O)(=O)c3c(C)n[nH]c3C)C2)cc1
[c] O=C(Cc1ccccc1)NC(C(=O)O)C(O)c1ccc([N+](=O)[O-])cc1
[d] O=C(/C=C/c1ccc(Cl)cc1Cl)N1CCN(c2ccc([N+](=O)[O-])c(N3CCOCC3)c2)CC1
Answer: c. O=C(Cc1ccccc1)NC(C(=O)O)C(O)c1ccc([N+](=O)[O-])cc1
