Task: Answer the multiple choice question.
Question: Which drug has a -21.577\% 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. COc1ccccc1N1CC(O)=C(c2nc3ccccc3s2)C1=N
b. C=CCn1c(SCC(=O)Nc2c(C)n(C)n(-c3ccccc3)c2=O)nc2sc(C)c(C)c2c1=O
c. COCCC(=O)Nc1ccc2c(c1)CN(C(=O)CSC)CC2
Answer: b. C=CCn1c(SCC(=O)Nc2c(C)n(C)n(-c3ccccc3)c2=O)nc2sc(C)c(C)c2c1=O
