B Correct answer
Explanation

Phosphoric acid in cola does have acidic properties, and experiments have shown that cola can dissolve iron nails over time. The 14-day timeframe is plausible given the pH level of cola (around 2.5-3.5) and its phosphoric acid content. The acidic reaction with iron is a documented phenomenon.
