Problem statement: Answer the multiple choice question.
Query: Which drug has a 3.939\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. O=C(Nc1nc2cc(Cl)ccc2s1)C1CCCN(S(=O)(=O)c2cccc3cccnc23)C1
b. COc1ccc(-c2c(C)nn(-c3ccccc3)c2N)cc1OC
c. CN1C(=O)c2ccc(N3CCCC3)cc2C1=O
Answer: b. COc1ccc(-c2c(C)nn(-c3ccccc3)c2N)cc1OC
