Answer: Option A.
Polar ice cap in Antarctica.
Explanation:
Scientist drill ice cores from inside the polar ice cap in Antarctica to study variability of climate and differentiate that variability From global climate change. Each layer of the ice tells about weather and what the Earth was like when the first snow fell.
For example, Le grande says that as snow deposits into a growing glacier, the temperature of the air imprints on water molecules.
Icy layers hold particles,aerosols, sea salts, trace elements that were in the atmosphere before and they abide for thousands of years and provide evidence of past events.

Hydrosphere
Explanation:
- The dolphin swims in the hydrosphere.
- The hydropshere is the region occupied by water on the earth surface.
- They are the oceans, lakes, rivers, glaciers e.t.c
- The hydrosphere makes up 70% the total surface area on earth.
- Ocean occupies a whooping 95% of all.
- The hydrosphere is able to support aquatic life and this is why the dolphin with its streamlined body swims in this sphere.

Robert Hooke observed the cells through a combination of lenses.
After Robert Hooke, the development of microscopy take place. After the development of the microscopy, scientist were able to observe the features of the cell. In order to formulate a cell theory observation of most of the cells was necessary. So, it was necessary to observe different types of cells from different organism. So, the advancement of the microscopy and observation process required for the formulation of the cell theory was the reason for the delayed development of the cell theory.
