Task: Answer the MCQ question.
Query: Which drug has a 5.429\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. COC(=O)C1=C(c2ccc(F)cc2F)C[C@@H]2CC[C@H]1N2C(=O)NCCOc1ccc(OC)cc1
b. CC(C)(C)C(=O)c1sc(Nc2ccccc2)nc1N
c. COc1cc(-c2nnc(SCC(=O)/C(C#N)=C(\C)N)o2)cc(OC)c1OC
Answer: c. COc1cc(-c2nnc(SCC(=O)/C(C#N)=C(\C)N)o2)cc(OC)c1OC
