Task: Answer the multiple-choice question.
Query: Which drug has a 3.169% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CCN(CC)c1ccc(N2C(=O)/C(=C\c3cccnc3)SC2=S)cc1
b. O=C(COc1ccccc1[N+](=O)[O-])N/N=C/C=C/c1ccco1
Answer: b. O=C(COc1ccccc1[N+](=O)[O-])N/N=C/C=C/c1ccco1
