Select the correct sequence for the production of somatic hybrid plants in somatic hybridization.
$I -$ Isolation of protoplasts
$II -$ Digestion of cell wall
$III -$ Regeneration of somatic hybrid plants
$IV -$ Isolation of cells
$V -$ Fusion of protoplasts of two different varieties
$VI -$ Formation of hybrid protoplasts

• A
  $IV \rightarrow II \rightarrow I \rightarrow V \rightarrow VI \rightarrow III$
• B
  $IV \rightarrow I \rightarrow II \rightarrow V \rightarrow VI \rightarrow III$
• C
  $IV \rightarrow V \rightarrow VI \rightarrow II \rightarrow I \rightarrow III$
• D
  $IV \rightarrow V \rightarrow VI \rightarrow I \rightarrow II \rightarrow III$
