Choose true and false statements from the following and select the correct option from the set $(A-D)$ given below:
$I.$ Diffusion is an important process of transport in plants since it is the only means for gaseous movement within the plant body.
$II.$ In active transport,pumps are proteins that use energy to carry substances across the cell membrane against the concentration gradient.
$III.$ In facilitated diffusion,special proteins help hydrophilic substances to be transported across the membrane.
$IV.$ In diffusion,molecules move against the concentration gradient in a random manner.
$V.$ Facilitated diffusion is faster than active transport.

• A
  $I, II, III$ are true,$IV$ and $V$ are false.
• B
  $I, II, III$ are true,while $IV$ and $V$ are false.
• C
  $IV$ and $V$ are true,while $I, II$ and $III$ are false.
• D
  Only $II, III, IV$ are true while $I$ and $V$ are false.
