Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 10.260\% 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(CSc1nnc2c(Cl)cc(C(F)(F)F)cn12)Nc1ccc2c(c1)OCO2
b O=C(NNC(=O)c1oc2ccccc2c1-n1cccc1)c1ccco1
Answer: b. O=C(NNC(=O)c1oc2ccccc2c1-n1cccc1)c1ccco1
