Problem statement: Answer the multiple choice question.
Question: Which compound has a -68.122\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. CN1CCN(Cc2ccccc2Sc2ccccc2)CC1.O=C(O)/C=C\C(=O)O
b. Cn1c2c(c(=O)n1-c1ccccc1)CSCC2
c. CC(C)(C)c1ccc(C(=O)OCC(=O)N2CCC(c3ccccc3)=N2)cc1
d. COc1ccccc1[C@@H]1C(c2ccc(F)cc2)=NN(c2ccccc2)[C@H]1C(=O)N1CCOC1=O
e. COc1ccccc1N1CCN(CCCNC(=O)Nc2ccccc2)CC1
Answer: a. CN1CCN(Cc2ccccc2Sc2ccccc2)CC1.O=C(O)/C=C\C(=O)O
