Problem statement: Answer the multiple choice question.
Question: Which drug has a 12.876\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) O=C(NC1CC1)C1CCN(S(=O)(=O)c2cc([N+](=O)[O-])ccc2Cl)CC1
b) Cc1ccc(OCC(=O)NNC(=O)C2CCCO2)c(C)c1
c) Cc1ccc(C2C(C(=O)c3cccs3)=C(O)C(=O)N2CCN2CCOCC2)o1
d) CCCCOc1ccc2c(c1)/C(=C(\C(Cl)=C(Cl)Cl)[N+](=O)[O-])N2
Answer: d. CCCCOc1ccc2c(c1)/C(=C(\C(Cl)=C(Cl)Cl)[N+](=O)[O-])N2
