Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.780% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a O=C(CSc1nnc(NC2CCCCC2)s1)Nc1ccc(N2CCOCC2)cc1
b Cc1cccc(OCCn2c(-c3ccco3)nc3ccccc32)c1
Answer: a. O=C(CSc1nnc(NC2CCCCC2)s1)Nc1ccc(N2CCOCC2)cc1
