Task: Answer the multiple choice question.
Question: Which compound has a 18.270\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) O=C(c1ccco1)N1N=C(c2ccc(Br)cc2)CC1c1ccco1
(b) CON(C)S(=O)(=O)c1cccc(C(=O)Oc2ccc(N(C)S(=O)(=O)c3ccccc3)cc2)c1
Answer: a. O=C(c1ccco1)N1N=C(c2ccc(Br)cc2)CC1c1ccco1
