Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.852\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=C(O)CC1S/C(=N\N=C2\C(=O)Nc3ccccc32)N(c2ccc(O)cc2)C1=O
(b) N#CC1=C(N)NC(=S)C(C(N)=O)C1c1ccc([N+](=O)[O-])cc1
(c) Cc1ccc(C2C3=C(CC(C)(C)CC3=O)OC3=C2C(=O)CC(C)(C)C3)cc1
(d) Cc1cccc(CSc2nc3c(cc2C#N)CN(C)CC3)c1
Answer: b. N#CC1=C(N)NC(=S)C(C(N)=O)C1c1ccc([N+](=O)[O-])cc1
