Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.472\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COC(=O)c1cn(NC(=O)C2COc3ccccc3O2)c(=O)c2ccccc12
b: CCCOc1ccc(/C(CC)=N/NC(=O)C2(C)CC2(Br)Br)cc1
c: O=C1CC(N2CCN(S(=O)(=O)c3ccccc3)CC2)C(=O)N1c1ccccc1
Answer: a. COC(=O)c1cn(NC(=O)C2COc3ccccc3O2)c(=O)c2ccccc12
