  1. $\text{‘1 3 4’}$ means ‘you are well’,
  2. $\text{‘7 5 8’}$ means ‘they go home’,
  3. $\text{‘8 3 9’}$ means ‘we are home’,

Which of the statement can be dispensed with while answering the above question?

We can find the code for 'home' from the second and third statements.

For finding the code for 'they', we need the code for 'go' which cannot be determined from the given data.
Clearly, statement $A$ is not necessary.

So, the correct answer is $(A).$
