**Answer:**

3 is the answer. for the given problem

**Step-by-step explanation:**

Given six digit number = 54321A

A number is divisible by 9, if the sum of all the digits in the given number is divisible by 9.

Sum of the digits = 5+4+3+2+1+A

= 15+A

So,The multiple of 9 after 15 is 18.

therefore the value of A must be 3

Now ,sum of the digits = 5+4+3+2+1+3=18

18 is divisible by 9

543213 is also divisible by 9
