Task: Answer the MCQ question.
Question: Which drug exhibits a 13.522\% 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 other words.
Options:
a: COc1ccc(-c2cc(-c3ccco3)[nH]c(=O)c2C#N)cc1OC
b: Cc1c(CNC2CCC(C)CC2)c(C(=O)O)c(C)n1Cc1ccccc1
c: Cn1c(CC(=O)Nc2ccc(Cl)c(Cl)c2)nnc1SCC(=O)NCc1ccccc1
d: O=C(Nc1ccccc1)OCc1cc(-c2ccc(Cl)cc2)on1
e: O=C(O)c1[nH]c2ccccc2c1C=NCc1ccccc1Cl
Answer: a. COc1ccc(-c2cc(-c3ccco3)[nH]c(=O)c2C#N)cc1OC
