Task: Answer the multiple choice question.
Query: Which drug has a 6.412\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CCOC(=O)C1CCCN(c2c(NCCCN(CC)c3ccccc3)c(=O)c2=O)C1
b: O=S(=O)(Nc1ccc(-c2nc3cccnc3s2)cc1)c1ccc(Cl)s1
c: O=C(c1ccccc1)c1nc2ccccc2[nH]c1=O
Answer: b. O=S(=O)(Nc1ccc(-c2nc3cccnc3s2)cc1)c1ccc(Cl)s1
