Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 6.160\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) O=C(CSc1nc2[nH]ncc2c(=O)n1-c1ccc(Cl)c(Cl)c1)NCc1ccccc1Cl
b) CCN(CC)c1ccc(/C=N/NC(=S)NCc2ccccc2)c(O)c1
Answer: a. O=C(CSc1nc2[nH]ncc2c(=O)n1-c1ccc(Cl)c(Cl)c1)NCc1ccccc1Cl
