Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.667\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CCOc1ccccc1C1CC(=O)NC(SCC)=C1C#N
b CCn1cc([N+](=O)[O-])c(C(=O)N2CCCCCC2)n1
c O=C(C1CCCN(c2ncnc3c2nc2n3CCCCC2)C1)N1CCN(c2cccc(Cl)c2)CC1
d Cc1c(C(C)(C)O)[nH]c2cc(C(F)(F)F)ccc12
Answer: b. CCn1cc([N+](=O)[O-])c(C(=O)N2CCCCCC2)n1
