Task: Answer the multiple choice question.
Question: Which compound exhibits a 13.263\% 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 Cc1c(NC(=S)N/N=C/c2ccc(O)cc2)c(=O)n(-c2ccccc2)n1C
b COc1cc2c(cc1OC)C1(Nc3c-2c(-c2ccccc2)nn3-c2ccccc2)C(=O)Nc2ccccc21
c O=C1CCCC2=C1C(c1cccs1)n1ncnc1N2
d O=C(c1ccc(Cl)cc1)N1CCN=C1c1ccccc1
Answer: b. COc1cc2c(cc1OC)C1(Nc3c-2c(-c2ccccc2)nn3-c2ccccc2)C(=O)Nc2ccccc21
