At what type of plate boundary is lithosphere created?

divergent

Explanation:

When two plates are moving away from each other, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the Earth and erupts to form new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges.

two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, which is known as subduction.

Explanation:

Deep trenches are often formed where tectonic plates are being subducted and earthquakes are common.  

i wanna say it’s between b and d, leaning more towards b.

i guess it’s a and b
