B Correct answer
Explanation

The PIN code system uses a 6-digit number where the first three digits represent the sorting district within a state. The first digit indicates the zone (9 zones in India), the first two digits together indicate the sub-zone, and the first three digits specifically identify the sorting district - the main post office that handles mail for that region. The last three digits identify the specific delivery post office.
