Task: Answer the multiple choice question.
Query: Which drug has a 12.174\% 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: CCOc1ccc(OCCCC(=O)Nc2nc3ccccc3[nH]2)cc1
b: CCOc1cccc(OCCCNCCCOC)c1
c: CC(Sc1cccc(C(F)(F)F)c1)C(=O)NC(N)=O
d: O=C(O)CCC(=O)c1cccc2ccccc12
e: NNC(=O)CNc1ccccc1Cl
Answer: e. NNC(=O)CNc1ccccc1Cl
