Task: Answer the MCQ question.
Question: Which compound exhibits a 16.115\% 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: COc1cccc(NC(=O)CCC(=O)NCc2ccco2)c1
b: Cc1c(N(C(=O)c2cnccn2)C2(C(=O)NC3CCCC3)CCCCC2)c(=O)n(-c2ccccc2)n1C
c: CCOc1ccc(-c2csc(/C(C#N)=C\c3ccc(O)c([N+](=O)[O-])c3)n2)cc1
d: O=C(Oc1cccc(NC2=NS(=O)(=O)c3ccccc32)c1)c1ccncc1
e: Cc1ccc(C(C(=O)NC2CCCCC2)N(C(=O)c2csnn2)C2CC2)o1
Answer: c. CCOc1ccc(-c2csc(/C(C#N)=C\c3ccc(O)c([N+](=O)[O-])c3)n2)cc1
