The correct answer is (2) - Stratosphere.
Ozone is found in the stratosphere , a layer beginning between 6 and 10 miles above the earth's surface and extends upward to about 30 mile above the surface of he earth.
The ozone that is found in the stratosphere absorbs most of he harmful ultraviolet sunlight and is thus called the "good ozone"
Ozone is also found in the lower region of the atmosphere known as the troposphere. But the ozone here strongly reacts with molecules causing toxicity in plants. The ozone is therefore termed as "bad ozone."
The answer to this question would be hypertonic.
If the chloroplast is going to be pushed against the cell wall, probably the water around the cell wall is decreased, causing it to suck up the water inside. Then, the solution must be causing the cell to lose water. The cell will lose water if put in a hypertonic solution. In a hypertonic solution, the osmotic pressure of the solution is higher than the cell, make it attract water from cells.
