Match the names of items listed under column $I$ with the items given under column $II$; choose the answer which gives the correct combination of the alphabets of the two columns.

Column $-I$	Column $-II$
$(A)$ Ketone	$(p)$ Has $5$ carbon sugar,a phosphate group and a nitrogenous base
$(B)$ Fatty acid	$(q)$ Has long chain of carbon and hydrogen atoms and a carboxyl group at one end
$(C)$ Aldehyde	$(r)$ Has a carbonyl group at the end of the carbon chain
$(D)$ Nucleotide	$(s)$ Has a carbonyl group within the carbon chain

• A
  $A = s, B = q, C = r, D = p$
• B
  $A = q, B = r, C = s, D = p$
• C
  $A = s, B = r, C = q, D = p$
• D
  $A = r, B = q, C = s, D = p$
