  • I. "Y" hormone induces flowering in mango and also promotes rapid internode / petiole elongation in deep water rice plants and hence helping leaves or upper part of shoot above water. II. "X" hormone promotes root growth and root hairs formation III. "Z" hormone inhibits the seed germination, increases the tolerance of plant to various stresses, play important role in seed development, maturation and dormancy. Identify the correct names of hormones

    A
    Y = ABA, X = Auxin, Z = GA
    B
    Z = GA, X= Auxin, Y = `C_2 H_4`
    C
    Y = Auxin, X = `C_2 H_4`, Z= GAA
    D

    Read the given statements and identify the plant hormones X,Y and Z. (i) Hormone Y induces flowering in mango and also promotes rapid internode/petiole elongation in deep water rice plants and hence helping leaves or upper part of shoot to remain above water. (ii) Hormone X promotes root growth and root hair formation. (iii) Hormone Z inhibits the seed germination, increases the tolerance of plant to various stresses, play important role in seed development, maturation and dormancy.
