The right option is a. variations.
Variations are the differences between the individual organisms of the same species which is as a result of genetic differences or the influence of environmental factors on the expression of the genetic abilities. Variation may be expressed in behavior, physical appearance, learning, and metabolism. The two types of variations are somatic variation and germinal variation.

The organism to be identified
Explanation:
To identify the genetic makeup of an unknown organism, the nucleotide sequences fond in the Deoxyribonucleotide (DNA) of a known organism is matched to the DNA of some known organisms. If there is a certain degree of sameness in most of the matched parts, then the unknown organism can be said to be related to the known organism. This is a comparative study. 
To carry out this identification, items used include; primers, the PCR machine, test tubes, DNA polymerase, free nucleotides, etc.
