Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.428\% 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 CC(C)c1ccc(/C=C2\SC(=O)N(CC(=O)NCCCn3ccnc3)C2=O)cc1
b COC(=O)c1ccc(-c2ncc[nH]2)cc1
c CCc1cc2ccccc2[nH]c1=S
d N/C(=N\OC(=O)c1ccccc1Cl)c1cccc([N+](=O)[O-])c1
e Cc1ccc(-n2c(=O)[nH]c3c(C(N)=O)nc(C(C)C)nc32)cc1
Answer: c. CCc1cc2ccccc2[nH]c1=S
