Task: Answer the multiple choice question.
Question: Which drug has a 4.170\% 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 additional words.
Options:
a: COCCCNC(=O)CN(c1cccc(Cl)c1)S(C)(=O)=O
b: Cc1ccc(Cl)cc1NC(=O)COC(=O)C1CCCCC1
c: N=c1oc2ccc3ccccc3c2cc1-c1nnc2n1CCCCC2
d: COC(=O)C(O)(NC(=O)OCc1ccccc1)C(F)(F)F
Answer: d. COC(=O)C(O)(NC(=O)OCc1ccccc1)C(F)(F)F
