Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -5.003\% 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(Oc1cc(-c2ccccc2)no1)c1ccc(F)cc1
b. O=C(Nc1ccccc1N1CCOCC1)c1ccccc1NS(=O)(=O)c1ccc(F)c(F)c1
Answer: a. O=C(Oc1cc(-c2ccccc2)no1)c1ccc(F)cc1
