Mitochondria is described as the power house of the cell, because it is the cell organelle that process the production of ATP, which is the energy source of the cell. Kreb's cycle occurs in the mitochondria, it is the process by which energy is generated inside the cell, leading to the production of ATP and carbon dioxide and water are given up as waste products.

B. Ice-albedo feedback
Explanation:
The ice-albedo feedback is one process that can significantly increase the rate of greenhouse emissions in response to a decreased albedo. 
Albedo is the ratio of reflected light to incident light. 
A decrease in albedo suggests that a surface is absorbing more light than it is reflecting. This is typical of areas with land cover and vegetation. 
Areas with a high reflectivity have a high albedo. Snow, ice and polar regions are good reflectors of solar radiation. They have a very high albedo close to 100%. Much of the surface area is buried with ice. 
Examples of greenhouse gases are carbon dioxide, methane, water vapor e.t.c 
How does a low albedo relates to increase in greenhouse gas emission? 
- The ice-albedo feedback can substantially contribute to greenhouse gas emission. 
- The high reflectivity of ice causes long wave radiation to warm the air around a icy body in polar regions. 
- When ice melts, they leave land bare and exposed.
-  Melt water collects in pockets. 
- Exposed land leads to a decrease in albedo. 
- Organisms can thrive more in warm terrain. 
- Also, pockets of carbon dioxide gases trapped in ice is released. 
- Organisms release carbon dioxide into the atmosphere during cellular respiration. 
- Soils originally permafrost will become stable and this will encourage more human occupation of the area. 
- All these activities leads to an increase in the emission of greenhouse gases in an area with low albedo.

Hi.
The structure which is present in both of those cells is:
D. Plasma membrane.
Vacuoles are only in eukaryotic cells. The same with Golgi complex and nucleus. 
Hope it helps!
