I want to know the answer to the following question:
Along with k and z, what Latin letter was not used in Old English?
All the background I'm provided with is that "The Latin alphabet of the time still lacked the letters ⟨j⟩ and ⟨w⟩, and there was no ⟨v⟩ as distinct from ⟨u⟩; moreover native Old English spellings did not use ⟨k⟩, ⟨q⟩ or ⟨z⟩.". Is that enough to answer the question?
Answer: yes
