Task: Answer the multiple choice question.
Question: Which drug exhibits a 15.773\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) O=C1CN(C(=O)c2ccc(Cl)c(S(=O)(=O)N3CCc4ccccc43)c2)c2ccccc2N1
b) C=CCNC(=O)C1CC2c3ccccc3C1c1ccccc12
Answer: b. C=CCNC(=O)C1CC2c3ccccc3C1c1ccccc12
