A micronutrient is the one which is

  • A
    More important than any major elements and are boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), magnesium (Mg), molybdenum (Mo), and zinc (Zn).
  • B
    Less important than major elements and are boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), and zinc (Zn) and phosphorous (P)
  • Correct answer
    C
    Needed in small quantity but is as important as a major element and are boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), and zinc (Zn).
  • D
    Found small quantities in the soil and are boron (B), chlorine (Cl), copper (Cu), iron (Fe), magnesium (Mg), molybdenum (Mo), and zinc (Zn) and calcium (Ca).

Solution

Essential elements required in large quantities are called macro and those required in small quantities are called micronutrient. Essential elements are very much necessary for normal growth and reproduction of the plant, they participate directly in the metabolic reaction, and their deficiency results in deficiency symptoms. The important microelements are boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), and zinc (Zn).

Hence, the correct answer is option: 'C'.
