Task: Answer the multiple-choice question.
Question: Which compound has a 29.454% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=C(NCc1ccccc1Br)c1ccncc1
[b] O=C(O)c1cc(-c2cc(C(=O)O)c3ccccc3n2)nc2ccccc12
[c] CN(C)S(=O)(=O)c1cccc(COc2cccnc2[N+](=O)[O-])c1
Answer: a. O=C(NCc1ccccc1Br)c1ccncc1
