I often see the sentences below and I am confused the proper usage for each one and which ones are grammatically wrong.
- The expense claimed were related to your income producing activity and therefore it was tax deductible.
- The expense claimed related to your income producing purpose and therefore it was tax deductible.
- The expense claimed were relating to your income producing purpose and therefore it was tax deductible.
- The expense claimed relating to your income producing purpose was tax deductible.
Appreciate if you could shed some lights.
