Task: Answer the multiple choice question.
Query: Which drug has a 2.485\% human ether-à-go-go related gene (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: COc1ccc(N/C=C\C(=O)c2ccc3ccccc3c2)cc1
b: O=P(O)(COc1ccccc1)COc1ccccc1
c: O=C(NNC(=O)c1ccccc1F)c1ccc(-c2ccc(Cl)cc2)o1
Answer: b. O=P(O)(COc1ccccc1)COc1ccccc1
