Passage
For many years, ship captains navigating the waters of Antarctica have been intrigued by sightings of emerald icebergs. Scientists have now explained their mystery. These icebergs are turned upside down. Icebergs are blocks of ice that have broken off huge slabs of frozen snow called ice shelves. Their green appearance results from sea water that has frozen at the bottom over hundreds of years. The frozen sea water has dissolved organic matter which gives it a yellow tone and the fresh water ‘ice shelf’ above has a blue tinge. When the iceberg turns upside down, it appears green through the visual mix of yellow with the blue from below.

What are ice shelves?

- They are pieces of ice which look like shelves
- They are huge pieces of ice which are very old
Answer and explanation
Correct answer: A - They are huge pieces of chunks of ice
The passage says icebergs break off 'huge slabs of frozen snow called ice shelves', i.e. huge pieces of ice. They are not frozen sea water (that is the bottom layer), nor described as old or shelf-shaped.
