The correct answer is: A-Cities on the ocean would be in danger of flooding.
Melting of ice caps can cause excessive flooding which is very dangerous as it would destroy homes, habitats, and lives. Polar ice caps and ice glaciers which are on higher altitudes melt faster and consequently raise river water levels as well causing floods. Other consequences of ice cap melting are:
• Climate change (warming)
• Shortage of Fresh Water
• Rise in sea level
• Reduced Agricultural Output.
