Match the following columns correctly:

Column-$I$	Column-$II$
$(a)$ Passive transport	$(p)$ Movement from higher concentration to lower concentration, no energy required
$(b)$ Active transport	$(q)$ Movement along the concentration gradient, requiring carrier proteins
$(c)$ Facilitated diffusion	$(r)$ Movement against the concentration gradient, requiring energy
$(d)$ Osmosis	$(s)$ Diffusion of solvent molecules across a semi-permeable membrane

• A
  $(a-p), (b-r), (c-q), (d-s)$
• B
  $(a-r), (b-q), (c-s), (d-p)$
• C
  $(a-q), (b-p), (c-r), (d-s)$
• D
  $(a-s), (b-r), (c-p), (d-q)$
