The answer is B) volcanic arc, island arc.
The first one would be island arc as subduction occurs beneath the continental crust. When it occurs, the compressional force placed upon the continential plate will cause the rock to bend and arc up form a series of volcanoes leading to the formation of volcanic arc.
The second one would be island arc as subduction occurs beneath the oceanic lithosphere. When subduction forced the crust to bend, rocks are compressed and arc up, forming a series of island, the formation of island arc then occurs.
C and D is incorrect as no transformation has take place.

Answer:
Forms of carbon differ in the oceans.
Explanation:
Two different primary types of carbon exist in the oceans.
- Carbonates - organisms in the ocean absorb carbon dioxide and produce carbonates CO₃²⁻. Calcium and magnesium ions combine with carbonates to form <u>calcium carbonate</u> that make up the bulk of corals and seashells plus <u>magnesium carbonate</u>.
When atmospheric CO₂ dissolves directly into the seawater, carbonic acid is produced, that reduces the pH of seawater.
One of the earth's precious diverse ecosystems comprises of coral reefs. Coral reefs' body is made up of calcium carbonate. However, calcium carbonate acts as a buffer. That's why, as pH decreases, the dissolution of calcium carbonate (corals structure and seashells) increases. It results in a massive extinction of coral ecosystem.
Hence, we should not disturb the balance of nature.
Quebecois French is b) diverged from Parisian French. However, this is only historically speaking and only pertains to the 17th century "koine" of Paris. Nowadays, the distinction between French from France and French from Quebec is huge and the accent stands out very strong compared to other dialects of French. However, the Quebecois are very proud of their language and do not want to standardize, as they feel it would be a removal of their culture.
