Given below are two statements.
Statement I: Plants that are adapted to dry tropical regions show C₄ pathway. 
Statement II: The Calvin cycle is the basic pathway that forms sugars in both C₃ and C₄ plants.
In light of the above statements, choose the correct answer from the options given below.

C₄ plants are plants that have evolved a specialized carbon fixation pathway known as the C₄ pathway. They are commonly found in environments with high temperatures and strong sunlight, such as dry tropical regions. The C₄ pathway is an adaptation to reduce the wasteful effects of photorespiration and increase water-use efficiency in such conditions.

The Calvin cycle, also known as the light-independent reactions or the dark reactions, is a common pathway found in both C₃ and C₄ plants. It is the primary pathway responsible for converting carbon dioxide (CO₂) into organic compounds, particularly sugars like glucose.
