• A. A - 1 , B - 2 , C - 3 , D - 4
• B. A - 4 , B - 3 , C - 2 , D - 1
• C. A - 3 , B - 4 , C - 2 , D - 1
• D. A - 3 , B - 1 , C - 4 , D - 2

Answer 1

The correct option is D A - 3 , B - 1 , C - 4 , D - 2

Necessary conditions for growth are water, oxygen, nutrients, temperature, light etc.
Water helps in cell enlargement and growth. Water is needed for photosynthesis, for transport of minerals and materials, maintaining the turgidity of the cell; which helps in the opening and closing of stomata.
Oxygen helps in releasing metabolic energy.
Nutrients are required for the synthesis of protoplasm. Macro and micronutrients that are required for all the different physiological activities of the plant, therefore these mineral nutrients are also essential for plant growth.
Optimum temperature is suited for best growth because all the growth processes are due to various metabolic activities that are carried out by different enzymes that are active only in the optimum temperature range.
