c. it made railroads unnecessary.

Explanation:

• Option A: The Panama Canal's main role isn't to make American ships popular; it's about trade routes, so A is incorrect.
• Option B: The canal connects Atlantic and Pacific, not primarily for South America trade ease, so B is wrong.
• Option C: Railroads still had uses, and the canal didn't make them unnecessary, so C is incorrect.
• Option D: The Panama Canal's key impact on commerce is shortening the voyage between the Atlantic and Pacific Oceans, reducing travel time and costs for trade, which boosted commerce.

Answer:

D. It shortened the journey between the Atlantic and Pacific Oceans.
