Task: Answer the MCQ question.
Question: Which drug exhibits a -3.540\% 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] COc1ccc(Cc2nnc(SCC(=O)N(C)c3ccccc3)o2)cc1
[b] COc1ccc(N(CC(=O)O)S(=O)(=O)c2ccc(C)cc2)cc1Cl
[c] CCN=C1S/C(=C\c2ccc(Sc3ccc(Cl)cc3)o2)C(=O)N1CC
Answer: c. CCN=C1S/C(=C\c2ccc(Sc3ccc(Cl)cc3)o2)C(=O)N1CC
