Answer
All the above statements are correct, thus the correct option is (d).
Work Step by Step
Nucleic acids are polymeric compounds formed by the combination of five nucleotides, namely Adenine (A), guanidine (G), cytosine (C), thymine (T) and Uracil (U). Among them DNA (deoxyribonucleic acid) has A, T, G and C, whereas RNA has A, U, G and C. The T is replaced with U in RNA. Each nucleotide contains a ribose sugar, a nitrogen base and a phosphate group. DNA has deoxyribose in its nucleotides, whereas RNA has ribose.
So, the options (a), (b) and (c) are correct. This means all the above statements are correct, thus the correct option is (d).
