Explanation:

• For Question 1: Photosynthesis uses carbon - dioxide ($CO_2$) and water to produce glucose and oxygen. So the statement is true.
• For Question 2: Sedimentary rocks like carbonates are the largest store of carbon on the planet. They contain a vast amount of carbon in the form of calcium carbonate and other carbon - containing minerals.
• For Question 3: The most abundant gas in the atmosphere is nitrogen (about 78%), not oxygen. So the statement is false.
