Explanation
Option B (4) is correct because telecommunications administrations are formally categorized into four distinct classes based on their scope, authority, and operational level - typically: international, national, regional, and local (or equivalent tiers depending on the regulatory framework).
Why the distractors are wrong:
- A (3) omits one administrative tier, often conflating regional and local levels into one category - an easy mistake but an incomplete picture of the full hierarchy.
- C (5) confuses this with the classic PSTN switching hierarchy (Class 1–5 offices), which is a network topology classification, not an administration classification.
- D (6) overcounts by further subdividing tiers that are not formally distinguished in standard telecom administration frameworks.
Memory tip: Think of the four classes as mirroring four geographic/authority levels - International, National, Regional, Local → "INRL" or "I Need Real Links" - four distinct levels, answer is 4.
