Task: Answer the multiple choice question.
Query: Which drug exhibits a 1.534\% 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 CCN(CC)S(=O)(=O)c1ccc(NC(=O)c2cnc(C)cn2)cc1
b O=c1[nH]c2ccc(S(=O)(=O)N3CCN(Cc4ccccc4)CC3)cc2[nH]c1=O
c O=C(CCC(=O)N(CC(=O)NC1CCCC1)c1ccccc1F)Nc1nccs1
d O=C(Nc1cccc([N+](=O)[O-])c1)Nc1ccc(Cl)cn1
Answer: c. O=C(CCC(=O)N(CC(=O)NC1CCCC1)c1ccccc1F)Nc1nccs1
