Explanation:

• At continental divergent boundaries, a rift valley is a common feature. Magma rises and pulls the continent apart, creating a long, low - lying area.
• Mountains that form underwater at oceanic convergent boundaries are trenches (not among the given options here but for context). At oceanic divergent boundaries, magma comes from the mantle.
• A well - known example of a continental divergent boundary is the East African Rift System. A well - known example of an oceanic divergent boundary is the Mid - Atlantic Ocean Ridge.

Answer:

• feature found at a continental divergent boundary: rift valley
• at an oceanic divergent boundary, this is where the magma is coming from: mantle
• best example of a continental divergent boundary: East African Rift System
• best example of an oceanic divergent boundary: Mid - Atlantic Ocean Ridge
