Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.012\% 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) COc1ccccc1NC(=O)CNC(=O)c1ccc([N+](=O)[O-])cc1
(b) C#CC[N+]1(CC#Cc2cccc3ccccc23)CCOCC1.[Br-]
(c) CC(OC(=O)Cc1c[nH]c2ccccc12)C(=O)N(C)c1ccccc1
(d) O=C(/C=C/c1ccc(OCCCF)cc1)Nc1ccnc(-c2cccnc2)n1
Answer: a. COc1ccccc1NC(=O)CNC(=O)c1ccc([N+](=O)[O-])cc1
