One contingency plan ABC could prepare for supply disruption of e-waste.

• A. Rely on a single supplier to keep costs low.
• B. Build relationships with multiple suppliers and keep safety stock where practical.
• C. Stop operations until supply returns.
• D. Increase prices to handle disruption without changing suppliers.

Answer: (B)

Contingency planning in supply chains means lining up prepared options so operations can keep going even if a disruption hits. For e-waste, having multiple suppliers and some safety stock gives resilience: if one supplier faces a shutdown or delays, others can step in, keeping collection and processing moving. Safety stock acts as a buffer so demand can be met while fresh deliveries catch up. This combination reduces the risk of a stockout and avoids costly shutdowns or forced price hikes. Relying on a single supplier creates a single point of failure, stopping operations is impractical, and simply raising prices doesn’t solve the disruption or ensure material comes in.
