The given question is incomplete as the options are missing. The options related to the given question are as follows-
(A) Crust is formed
(B) Mountains are formed
(C) Seafloor spreading occurs
(D) Crust becomes molten rock
(E) Denser plates slide under lighter plates
Answer:
Options (C), (D) and (E)
Explanation:
Trenches are usually defined as the V-shaped depressions that are formed in the convergent plate boundary, where the denser plate sinks below the lighter one.
These are usually extended up to a great depth, such as the the Mariana trench which is about 11 km deep. These trenches marks the boundary between the two plates.
In a convergent plate boundary, with a distinct deep oceanic trenches, the seafloor spreading takes places extensively, and the downgoing crust undergoes partial melting and becomes hot molten rocks that eventually mixes up with the magma.
Thus, the correct answers are options (C), (D) and (E).

Answer:
B.) Red Volcanic Rock
C.) Lava Rock covered by Sulphur
Explanation:
Igneous rocks are rocks that forms from the cooling and solidification of magma. Magma is a melt or molten rock. Magma is usually derived from rocks that have been buried and subjected to extreme temperature conditions.
Red volcanic rocks and lava rocks covered with sulphur are classified as volcanic rocks. Volcanic rocks are formed from magma that settles and cools on the surface of the crust. These magma is called lava.
Slate is a metamorphic rock and sandstones are sedimentary in nature.
the answer is b. i am pretty sure.
Can you show an image otherwise i cant help you
