Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.616\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) COc1ccc(OC)c(C(C)NC(=O)c2ccco2)c1
b) O=C(Cc1ccc(Cl)cc1)NNC1CC(=O)N(c2ccc3ccccc3c2)C1=O
c) CSCCC(NC(=O)c1ccccc1)C(=O)Nc1ccncc1
d) CCOC(=O)c1c(C)[nH]c(C)c1C(=O)COC(=O)CNC(=O)c1ccc(OCC)cc1
Answer: b. O=C(Cc1ccc(Cl)cc1)NNC1CC(=O)N(c2ccc3ccccc3c2)C1=O
