Question

what is the term that describes an element (such as carbon) that is \locked away\ and cannot be immediately used?

Explanation:

• Combustion is a process of burning, not about locking elements.
• Sequestration refers to the process of capturing and storing (locking away) an element like carbon so it's not immediately available for use.
• Respiration is a biological process of gas exchange, not related to locking elements.
• Biodiversity is about the variety of life, not about element storage.

B. sequestration
