A Correct answer
Explanation

Phosphoric acid in colas has a pH around 2.5-3.5, making it quite acidic. While experiments show it can corrode materials like nails over time, the '4 days' claim may be exaggerated or dependent on specific conditions - the key point is that cola phosphoric acid is strongly corrosive.
