Task: Answer the multiple choice question.
Question: Which drug has a 11.562\% 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(CSc1ccc2c(c1)OCCO2)Nc1ccc(N2CCOCC2)cc1
(b) COc1ccc(OC)c(C2C(C(C)=O)=C(O)C(=O)N2c2ccc(O)cc2)c1
Answer: a. O=C(CSc1ccc2c(c1)OCCO2)Nc1ccc(N2CCOCC2)cc1
