Solution

The correct option is A Micronutrients
Essential elements which are required in plants in traces only, equal or less than 0.1 mg/gm of dry matter are known as micronutrients. There are about seven nutrients essential to plant growth and health that are only needed in very small quantities. They are boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), chlorine (Cl). They constitute in total less than 1% of the dry weight of most plants.
Therefore, the correct answer is option A.
