Task: Answer the MCQ question.
Question: Which drug exhibits a 16.163\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CCc1cc2c(SCC(=O)NC3CCS(=O)(=O)C3)ncnc2s1
b: COC(=O)C1=C(C)N(c2ccc(Cl)cc2)/C(=C/c2ccc(O)cc2)C1=O
Answer: b. COC(=O)C1=C(C)N(c2ccc(Cl)cc2)/C(=C/c2ccc(O)cc2)C1=O
