The type of rock that can only form on or very near Earth's surface is A. Sedimentary.

Here's a step-by-step explanation:

1. Sedimentary rocks are formed from the accumulation of sediments, such as sand or small pieces of rock, that are deposited on the Earth's surface over time.

2. These sediments can come from the weathering and erosion of existing rocks, or from the remains of plants and animals.

3. Over time, these sediments are compacted and cemented together, forming sedimentary rock.

4. This process typically occurs in areas like riverbeds, oceans, and deserts where sediments can accumulate over time.

5. Therefore, sedimentary rocks can only form on or very near the Earth's surface, unlike metamorphic or igneous rocks, which require heat and pressure conditions typically found deep within the Earth.
