Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.905\% 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 additional words.
Options:
(a) COc1cc(S(=O)(=O)NC2CCCCC2C)ccc1F
(b) O=C(NN1CCOCC1)c1ccc(Cl)cc1Cl
(c) CCOc1cc(/C=N/N=C(\N)c2nonc2N)cc(Br)c1OCc1cccc2ccccc12
Answer: b. O=C(NN1CCOCC1)c1ccc(Cl)cc1Cl
