Explanation
B is correct because Tier 1 schedulers sit at the top of the scheduling hierarchy - by definition, no higher-tier scheduler exists above them. Instead of receiving bandwidth allocations, Tier 1 schedulers are themselves responsible for distributing bandwidth downward to lower-tier schedulers (Tier 2, Tier 3, etc.).
Why A is wrong: Saying Tier 1 schedulers must obtain bandwidth from a higher tier assumes something exists above them, which contradicts the meaning of "Tier 1" as the apex of the hierarchy. It is the lower tiers that obtain bandwidth from the tier above them, not Tier 1.
Memory tip: Think of Tier 1 as the CEO of a company - CEOs don't receive budget approvals from someone above them; they grant budgets downward. If a scheduler needs to ask a higher tier for bandwidth, it isn't Tier 1.
