Task: Answer the MCQ question.
Question: Which drug exhibits a 9.640\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) CCOC(=O)CN1C(=O)S/C(=C\c2ccc3c(c2)OCO3)C1=O
b.) COC(=O)CC1=C(C(=O)OC)C(c2ccc3c(c2Cl)OCO3)C(C#N)=C(N)O1
c.) Cc1c(Cl)c([N+](=O)[O-])nn1CC(=O)NCc1cccnc1
d.) O=C(CSc1nc2ccccc2n1S(=O)(=O)c1ccccc1)N1CCCCC1
e.) COc1ccc(NC(=O)c2cccc(NC(=O)c3ccccc3)c2)cc1
Answer: a. CCOC(=O)CN1C(=O)S/C(=C\c2ccc3c(c2)OCO3)C1=O
