Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 6.993\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a.) COc1ccc(NC(=O)C(c2cc3c(cc2[N+](=O)[O-])OCO3)N(C)C)cc1
b.) Cc1ccc(Cl)cc1N1CCN(S(=O)(=O)c2cc3c(cc2C)NC(=O)CO3)CC1
c.) O=C(NCCc1ccc(Cl)cc1)c1ccc2nc[nH]c2c1
d.) CCCC(NC(=O)CNC(=O)C(C)(C)C)C(=O)O
e.) CC(=O)N1CCC(=NNS(=O)(=O)c2ccc(C)c([N+](=O)[O-])c2)CC1
Answer: c. O=C(NCCc1ccc(Cl)cc1)c1ccc2nc[nH]c2c1
