The correct option is 1, which means that statements 1 and 2 are correct.

Statement 1: Chlorenchyma is formed by the palisade and spongy mesophyll. Palisade and spongy mesophyll are two types of plant tissues that are responsible for photosynthesis. The palisade mesophyll is located just below the upper epidermis and consists of tightly packed, column-shaped cells. The spongy mesophyll is located beneath the palisade mesophyll and consists of loosely arranged cells with air spaces between them.

Statement 2: Chlorenchyma is a form of parenchyma tissue that contains chloroplasts. Parenchyma tissue is the most common type of plant tissue and is involved in various functions, including photosynthesis. Chlorenchyma is specialized parenchyma tissue that contains chloroplasts, which are responsible for capturing sunlight and carrying out photosynthesis.

Statements 3 and 4 are incorrect. Statement 3 states that chlorenchyma serves to transport organic solutes made by photosynthesis, but in reality, the transportation of organic solutes is typically carried out by phloem tissue, not chlorench
