Problem statement: Answer the multiple choice question.
Query: Which compound has a 18.681\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) O=C(Nc1ccc(Oc2ccccc2)cc1)N[C@@H](Cc1ccccc1)C(=O)O
b) O=C(CN1CCOCC1)Nc1c2c(nc3c1CCC3)CCC2.O=C(O)C(=O)O
c) CCOc1ccccc1NC(=S)N(Cc1cc2ccc(C)cc2[nH]c1=O)CC1CCCN1CC
d) CN(C)CC/C=C1/c2ccc(F)cc2Sc2ccc(Cl)cc21.Cl
e) COc1cc(/C=N/Nc2ccccn2)cc(OC)c1O
Answer: a. O=C(Nc1ccc(Oc2ccccc2)cc1)N[C@@H](Cc1ccccc1)C(=O)O
