Task: Answer the MCQ question.
Query: Which drug exhibits a 1.572\% 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, c, d, or e without using any additional words.
Options:
a. CC/C=C/C(=O)N1CC2(CC(c3cccc(NC(=O)CC(c4ccccc4)c4ccccc4)c3)=NO2)C[C@@H]1C(N)=O
b. CCN(CC)S(=O)(=O)c1ccc(N2CCCC2)c(NC(=O)c2nn(C)c(=O)c3ccccc23)c1
c. COc1ccc(C2/C(=C(/O)c3ccc(C)cc3)C(=O)C(=O)N2c2ccccn2)cc1
d. O=C(NC1CCCCC1)C(c1ccccc1)N(Cc1ccc2c(c1)OCO2)C(=O)c1cnsn1
e. CCOC(=O)Cn1nc(-c2ccc(Cl)cc2)ccc1=O
Answer: e. CCOC(=O)Cn1nc(-c2ccc(Cl)cc2)ccc1=O
