Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.255\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. O=C(COc1ccccc1[N+](=O)[O-])N/N=C/c1ccncc1
b. COc1ccccc1C(=O)Nc1cc2cc(Cl)ccc2oc1=O
c. COc1ccc(C(=O)NC(=S)Nc2ccc(Cl)cn2)cc1OC
Answer: b. COc1ccccc1C(=O)Nc1cc2cc(Cl)ccc2oc1=O
