Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.402\% 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(CCCN1C(=O)C(c2ccccc2)Oc2cccnc21)NCc1ccc(F)cc1
b) O=C1CN(C(=O)CSc2nnc(C3CC3)n2-c2ccccc2)c2ccccc2N1
Answer: a. O=C(CCCN1C(=O)C(c2ccccc2)Oc2cccnc21)NCc1ccc(F)cc1
