Task: Answer the MCQ question.
Query: Which compound exhibits a 13.671\% 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: COc1cc(OC)c(NC(=O)CCc2nc(-c3ccc(C)cc3)no2)cc1Cl
b: Cc1cccc(C)c1-n1c(C)cc(/C=N/NC(=O)CSc2ncccn2)c1C
c: CCOC(=O)CNC(=O)CSc1nc(-c2ccccc2)ns1
d: COC(=O)c1ccc2c(=O)n(Cc3ccc4c(c3)OCO4)c(=S)[nH]c2c1
e: O=C(Cn1nc(-c2ccccc2)c2ccccc2c1=O)Nc1cccc(O)c1
Answer: e. O=C(Cn1nc(-c2ccccc2)c2ccccc2c1=O)Nc1cccc(O)c1
