Task: Answer the MCQ question.
Question: Which drug exhibits a 16.218\% 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] COc1cccc(COC(=O)c2cc(=O)[nH]c3ccc(S(=O)(=O)N4CCOCC4)cc23)c1OC
[b] Cc1ccc(/C=N/NC(=O)C2=NNC(c3ccccc3)(c3ccccc3)C2)c(O)c1
[c] O=C(O)CNS(=O)(=O)c1cccc(Cl)c1
Answer: c. O=C(O)CNS(=O)(=O)c1cccc(Cl)c1
