What does "increase" mean?

The term "increase" refers to the action of growing or becoming larger in size, amount, or degree. It signifies a positive change where something elevates or expands. For instance, if company profits increase, it means they are rising compared to previous figures. This definition aligns clearly with everyday language and common understanding, making it the appropriate choice in this context.

The other options provide alternative meanings that do not reflect the definition of "increase." Describing a change to decrease or remain the same contradicts the essence of an increase, which inherently involves a rise or growth. Similarly, the idea of stopping suddenly does not capture the concept of growth or enlargement in any form. Therefore, understanding "increase" as a process of growth is essential.
