Step 1: Analyze the question The question asks which mode of transport is best for carrying perishable goods. These are items that spoil quickly, such as fresh fish, meat, fruits, vegetables, flowers and fresh milk.

Step 2: Explain the concept Perishable goods need transport that is:

• Fast, so the goods arrive before they spoil
• Reliable, with few delays
• Able to cover long distances quickly, especially for export

Step 3: Evaluate each option

• A. Air: This is the fastest mode of transport. It is ideal for goods that spoil quickly, such as fresh flowers, fruits and seafood exported from Nigeria to Europe. Its main disadvantage is high cost, but it is still the best for preserving perishables.
• B. Rail: This is cheap for bulky goods, but it is slow and has fixed routes and schedules. Perishables may spoil along the way.
• C. Road: This is flexible and offers door-to-door delivery. It is widely used for short distances in Nigeria, but it is slower over long distances and affected by traffic and bad roads. It is good, but not the best.
• D. Pipeline: This only carries liquids and gases such as crude oil, natural gas and water, so it is not suitable for perishable food goods in general.

Step 4: Answer Air transport is the fastest, so it reduces the time available for spoilage. The correct answer is A. air.

Tip: Link keywords to modes of transport:

• Perishable → fast → air
• Bulky and heavy → rail or water
• Door-to-door and short distance → road
• Oil, gas and water → pipeline
