Task: Answer the MCQ question.
Query: Which compound exhibits a 14.034% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCCNC(=O)c1nn2c(C(F)(F)F)cc(-c3ccccc3)nc2c1Br
b: O=C(COC(=O)C1CCN(S(=O)(=O)c2cccs2)CC1)Nc1ccccc1Br
c: COc1cc(/C=N/NC2=NCCCCC2)ccc1O.Cl
d: CCCn1c(SCC(=O)NC)nnc1C(C)C
e: O=C1CCC(=O)O1
Answer: e. O=C1CCC(=O)O1
