Explanation:

For the importance of water:

The correct options (checked) are:

• It ensures life on Earth can exist. (Water is essential for cellular processes, habitats, etc., supporting life.)
• It is used by plants for photosynthesis. (Plants use water in the photosynthesis reaction: \(6CO_2 + 6H_2O \xrightarrow[\text{Chlorophyll}]{\text{Sunlight}} C_6H_{12}O_6 + 6O_2\).)
• It is the main component of many biological components, including blood. (Blood is mostly water, and water is a major component of cells, tissues, etc.)

The incorrect option (crossed) is "It is a part of all organic compounds" because organic compounds typically contain carbon and hydrogen (and others), and water (\(H_2O\)) is inorganic.

For the importance of carbon:

The correct options to check are:

• It ensures life on Earth can exist. (Carbon - based molecules (organic compounds) are the basis of life's structures and functions.)
• It is a part of all organic compounds, including carbohydrates and nucleic acids. (Organic compounds are defined as compounds containing carbon (except some like \(CO_2\), carbonates), and carbohydrates (\(C_n(H_2O)_m\)) and nucleic acids (contain carbon - containing rings, sugars, etc.) are organic and have carbon.)
• It is found in every living thing. (All living organisms are made of organic molecules which contain carbon.)

The incorrect option is "It is the universal solvent" because water is the universal solvent, not carbon.

Final Answers:

Importance of Water (Checked Options):

• It ensures life on Earth can exist.
• It is used by plants for photosynthesis.
• It is the main component of many biological components, including blood.

Importance of Carbon (Options to Check):
