Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.925\% human ether-à-go-go related gene (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] CCOC(=O)C1CCCN(C(=O)c2cccc([N+](=O)[O-])c2C)C1
[b] Cc1ccc(-c2onc3ccc(C4OCCO4)cc23)cc1
[c] O=C(Cn1c(C(F)(F)F)nc2ccccc21)c1ccccc1
[d] CC(C)CC(=O)N1CCC(O)(CS(=O)(=O)Cc2ccccc2)CC1
Answer: c. O=C(Cn1c(C(F)(F)F)nc2ccccc21)c1ccccc1
