Explanation:

- Statement 1: Living beings can demonstrate growth and repair, which are essential features of life. Non-living beings, like rocks or man-made objects, cannot naturally grow or repair themselves.

- Statement 2: Metabolic processes, such as respiration, digestion, and energy production, occur only in living beings. Non-living beings do not perform metabolic activities.

- Option 1: "1 only" is incorrect because both statements accurately distinguish between living and non-living beings.

- Option 2: "2 only" is incorrect for the same reason as option 1.

- Option 3: "Both 1 and 2" is correct. Both statements provide a valid description of the differences between living and non-living beings.

- Option 4: "Neither 1 nor 2" is incorrect because both statements are indeed true.
