Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.168% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a COCCNC(=O)/C(C#N)=C/c1ccc(OCC(=O)NC2CCCCC2)cc1
b O=C(CSc1nc2nccnc2c(=O)n1Cc1cccs1)Nc1ccccc1F
Answer: a. COCCNC(=O)/C(C#N)=C/c1ccc(OCC(=O)NC2CCCCC2)cc1
