Problem statement: Answer the multiple choice question.
Question: Which drug has a 0.239% 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: O=C1Nc2ccc(Cl)cc2/C1=C/C1CC=CCC1
b: CCN(CC)CCCNC(=O)c1c(O)c2c([nH]c1=O)CCCC2
Answer: a. O=C1Nc2ccc(Cl)cc2/C1=C/C1CC=CCC1
