Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.871\% human ether-à-go-go related gene (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(NNC1=NCCC1)c1cccc(Br)c1
b CCSC1=C(C#N)C(c2ccc(C)s2)CC(=O)N1
Answer: b. CCSC1=C(C#N)C(c2ccc(C)s2)CC(=O)N1
