Question

A financial technology company's automated risk engine classifies flagged international wire transfers into three Compliance Escalation Tiers (Tier 1, Tier 2, or Tier 3) based on two parameters: Transaction Anomaly Score ($S$), measured on a scale from $1$ to $100$, and Counterparty Country Risk Index ($R$), categorized as Low ($R \le 30$), Medium ($30 < R \le 70$), or High ($R > 70$).

The engine applies the following hierarchical rules:
- Tier 1 (Immediate Hold): Assigned to any transaction with $S \ge 80$, or any transaction with $R > 70$ EXCEPT when $S < 40$ (which reassigns it to Tier 2).
- Tier 2 (Enhanced Verification): Assigned to any transaction not meeting Tier 1 criteria that satisfies at least one of the following conditions: $S \ge 50$, or Medium country risk ($30 < R \le 70$).
- Tier 3 (Standard Monitoring): Assigned to all remaining transactions.

A compliance officer evaluates two flagged transfers:
- Transaction Alpha: $S = 35$, $R = 85$
- Transaction Beta: $S = 85$, $R = 25$

Which of the following correctly pairs the Compliance Escalation Tiers for Transaction Alpha and Transaction Beta, respectively?
