Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.991% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) COc1ccc2nc(C(F)(F)Cl)c(C#N)c(N)c2c1
(b) C/C(=N\O)C(C)(C)Nc1cccc(Br)c1
(c) COC(=O)C(O)(NC(=O)OCc1ccccc1)C(F)(F)F
(d) C[C@@]12CCC=C[C@H]1[C@H](c1ccc(/C=C/c3ccccc3)cc1F)N(Cc1ccccc1)C2=O
Answer: a. COc1ccc2nc(C(F)(F)Cl)c(C#N)c(N)c2c1
