In angiosperms, the following events occur during megasporogenesis and megagametogenesis

$(i)$ Differentiation of megaspore mother cells

$(ii)$ Meiosis of the megaspore mother cell

$(iii)$ Formation of a linear tetrad

$(iv)$ Mitotic division of the functional megaspore

$(v)$ Degeneration of 3 megaspores

$(vi)$ Formation of embryo sac

$(vii)$ Fusion of polar nuclei

The correct sequence is

• A

  $v, i, ii, vi, vii, iii, iv$

• B

  $iv, iii, vii, vi, ii, i, v$

• C

  $v, i, ii, vii, vi, iv, iii$

• D

  $v, i, ii, vi, vii, iv, iii$
