Task: Answer the multiple-choice question.
Question: Which drug has a -8.531\% 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 other words.
Options:
a: CCN(CC)c1ccc2cc(C#N)c(=O)oc2c1
b: CCOC(=O)c1sc(NC(=O)c2ccc(S(=O)(=O)N3CCOCC3)cc2)cc1C
c: O=C(Nc1ccc(-c2nnc(-c3ccccc3)o2)cc1)c1ccc(Br)o1
Answer: c. O=C(Nc1ccc(-c2nnc(-c3ccccc3)o2)cc1)c1ccc(Br)o1
