Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 15.791\% 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: CC(NC(=O)Nc1ccc([N+](=O)[O-])cc1)C(c1ccccc1)N1CCOCC1
b: CC(C)N1CCN(Cc2cc3ccccc3[nH]2)CC1CCO
c: CC(=O)O.COc1ccc(Cn2c(-c3ccc(OC)cc3)[n+](CCCn3c(-c4ccc(F)cc4)nc4cc(C(F)(F)F)ccc43)c3ccc(C(=O)O)cc32)cc1
d: CCc1ccccc1NC(=O)C1CCN(S(C)(=O)=O)CC1
e: COc1ccc(C)cc1-n1c(SCC(=O)NCC2CCCO2)nc2c([nH]c3ccccc32)c1=O
Answer: c. CC(=O)O.COc1ccc(Cn2c(-c3ccc(OC)cc3)[n+](CCCn3c(-c4ccc(F)cc4)nc4cc(C(F)(F)F)ccc43)c3ccc(C(=O)O)cc32)cc1
