Final answer:
The correct homonym for the context is 'knight', and it is used correctly in sentence OB.
Step-by-step explanation:
The correct homonym for the context in this question is knight. Sentence OB, 'Mrs. Janowski has a meeting every knight', uses the homonym 'knight' correctly, referring to a medieval military servant. The other sentences use the incorrect homonyms: OA should use 'act' instead of 'out', C should use 'pair' instead of 'pear', and OD should use 'which' instead of 'witch'.
