Task: Answer the MCQ question.
Question: Which drug exhibits a 0.996\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CCOC(=O)C1=C(C)Nc2ccccc2N/C1=N\S(=O)(=O)c1ccc(Cl)cc1
b. COc1ccc(N2C(=O)CCC(C(C)=O)=C2C)cc1
c. Cc1ccccc1CC1(CO)CCCN(Cc2cn[nH]c2-c2ccccc2)C1
Answer: a. CCOC(=O)C1=C(C)Nc2ccccc2N/C1=N\S(=O)(=O)c1ccc(Cl)cc1
