Task: Answer the multiple choice question.
Query: Which drug has a -16.540\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a Cl.O=C(CN1CCCC1)Nc1ccc(OC(F)(F)F)cc1
b Cc1ccc(-c2nc3ccccc3c(C(=O)O)c2CC(=O)O)cc1
c CC(C)(C)c1ccc(OCCC(=O)Nc2cccc(S(=O)(=O)N3CCOCC3)c2)cc1
Answer: a. Cl.O=C(CN1CCCC1)Nc1ccc(OC(F)(F)F)cc1
