Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.414\% 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(NNC1=Nc2cc([N+](=O)[O-])ccc2OC1)c1ccccc1Cl
[b] Cc1c(NC2=CC(=O)CC(C)(C)C2)c(=O)n(-c2ccccc2)n1C
[c] CCOc1cccc2c1OC(c1cc(OC)c(OC)c(OC)c1)N1N=C(c3ccc(C)o3)CC21
[d] CCSc1nsc(NC(=O)Nc2cccc(OC)c2)n1
Answer: d. CCSc1nsc(NC(=O)Nc2cccc(OC)c2)n1
