The individuality of an organism is determined by the
A
sequence of nitrogenous bases in deoxyribonucleic acid
B
number of amino acids in a cell
C
position of the ribosomes on the endoplasmic resticulum
D
number of nitrogenous bases in a codon
Explanation: 

Detailed explanation-1: -The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences. DNA bases pair up with each other, A with T and C with G, to form units called base pairs.

Detailed explanation-2: -The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA.
