Task: Answer the multiple choice question.
Query: Which drug has a 4.257\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(c1cn(-c2ccccc2)nc1-c1ccccc1)N1CCN(c2ccccn2)CC1
(b) N#CC1=C(N)Oc2n[nH]c(-c3cccs3)c2C1C1C=CCCC1
(c) COC(=O)c1ccc(C)c(NC(=O)C2CC(=O)N(C3CCCC(C)C3C)C2)c1
Answer: b. N#CC1=C(N)Oc2n[nH]c(-c3cccs3)c2C1C1C=CCCC1
