Task: Answer the multiple choice question.
Question: Which drug has a 18.882\% 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)c1c(NC(=O)c2nc3ccccc3s2)sc2c1CCN(C(C)=O)C2
[b] COC(=O)Nc1ccc(S(=O)(=O)N2CCN(c3ccc(F)cc3)CC2)cc1
[c] CSc1ccccc1NC(=O)Nc1ccc(F)c(Cl)c1
Answer: a. COC(=O)c1c(NC(=O)c2nc3ccccc3s2)sc2c1CCN(C(C)=O)C2
