Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 15.203\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(Oc1cccc(-n2cnnn2)c1)c1ccccc1Cl
[b] Cc1cc(C)cc(NC(=O)COC(=O)CCCC2=NS(=O)(=O)c3ccccc3N2)c1
[c] COc1ccccc1CCn1cc(C#N)c(=O)[nH]c1=O
[d] CCOC(=O)c1c(NC(=O)C2COc3ccccc3O2)sc(C)c1C
Answer: c. COc1ccccc1CCn1cc(C#N)c(=O)[nH]c1=O
