Problem statement: Answer the multiple choice question.
Query: Which drug has a 16.358\% 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 N[C@@H](C(=O)N[C@@H]1C(=O)N2C(C(=O)O)=C(Cl)CS[C@H]12)c1ccccc1
b CC1CC(C)CN(CC(=O)N2CCc3[nH]c4ccccc4c3C2)C1
c C=CCn1c(SCc2cccnc2)nnc1-c1ccncc1
d COc1ccc(C2C(C#N)=C(SCC(=O)Nc3ccc(C)cc3)NC3=C2C(=O)CC(C)(C)C3)cc1
Answer: a. N[C@@H](C(=O)N[C@@H]1C(=O)N2C(C(=O)O)=C(Cl)CS[C@H]12)c1ccccc1
