Problem statement: Answer the multiple choice question.
Question: Which drug has a 0.537\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(N/N=C/c1cc([N+](=O)[O-])ccc1O)c1ccncc1
b: CCNc1ccc(Br)cc(C(=O)/C=C/c2ccc(OCC)cc2)c1=O
Answer: b. CCNc1ccc(Br)cc(C(=O)/C=C/c2ccc(OCC)cc2)c1=O
