Problem statement: Answer the multiple choice question.
Question: Which drug has a 12.188\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1cccc(-c2nnc(NC(C)=O)o2)c1
b: CCn1c(SCc2cccc(OC)c2)nc2ccccc2c1=O
c: COc1ccc(NC(=O)Cc2ccc(Cl)cc2)cc1NC(=O)c1ccco1
Answer: b. CCn1c(SCc2cccc(OC)c2)nc2ccccc2c1=O
