Detailed Solution

 The given statement is true.
Concept- Numbers in the form Question Image mean that each digit is displayed individually with  the variable. If the sum of all digits in a number is divisible by 3, then the rule of divisible 3 is used to indicate that the number itself is divisible by 3.
It is stated in the question that the number Question Image' is completely divisible by 3. This means that the numberQuestion Imagemeets the divisor rule of 3.  According to the law of divisor of 3, if the sum of all  digits of a number is divisible by 3, then the number itself is divisible by 3.  This means that Question Imageis also divisible by 3. So if you rearrange the numbers as  the sum of the numbers, Question Image, the numbers will be Question Image, which is the same  value as (a + b + c + d). Therefore, the second number Question Imageis also divisible by 3. This is because it meets the  rule of splitability of 3.
Hence, the correct answer is option (1).
