    The following are selected plant apomorphies:A. Development of xylem B. Development of cuticle C. Development of independent sporophyte D. Development
    Question

    The following are selected plant apomorphies:

    A. Development of xylem
    B. Development of cuticle
    C. Development of independent sporophyte
    D. Development of eustele

    Which option represents the correct evolutionary sequence of the above?

    A.

    A-D-B-C

    B.

    C-A-B-D

    C.

    B-C-A-D

    D.

    C-B-D-A

    Correct option is C

    Explanation-

    Evolutionary Timeline of These Features:
    B. Development of cuticle
            First adaptation as plants moved to land (seen even in non-vascular bryophytes).
            First to evolve
    C. Development of independent sporophyte
            In bryophytes, sporophytes are dependent gametophyte.
            Independent sporophytes arose in early vascular plants (like ferns)(Pteridophytes)
    A. Development of xylem
            Appears in vascular plants to transport water (e.g., lycophytes, ferns)(Pteridophytes).
    D. Development of eustele
            A more advanced vascular arrangement found in seed plants (gymnosperms & angiosperms).

    So the correct order is:
    B (cuticle) → C (independent sporophyte) → A (xylem) → D (eustele)

    This matches with option c: B → C → A → D
