Problem statement: Answer the multiple choice question.
Question: Which drug has a 14.940\% 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 COc1ccccc1NC(=S)N1CCc2cc(OC)c(OC)cc2C1
b CCCCN(C(=O)NC(=O)NC1C2CC3CC(C2)CC1C3)S(C)(=O)=O
c COc1ccc(-c2csc(/C(C#N)=C\c3cccc([N+](=O)[O-])c3)n2)cc1
d O=C(CNC(=O)c1ccccc1Cl)N/N=C/C=C/c1ccccc1
e Cc1sc2nc(CSCC(=O)NC3(C#N)CCCCC3)[nH]c(=O)c2c1C
Answer: c. COc1ccc(-c2csc(/C(C#N)=C\c3cccc([N+](=O)[O-])c3)n2)cc1
