Answer:
The correct option is C.
Explanation
Option A
Amines are the organic compounds which contain amino functional groups (-NH2), i.e 1-Propamine (CH3-CH2-CH2-NH2). so this is incorrect option.
Option B
Phosphate group is present in group of organic compounds known as organic phosphates. they are involved in energy transfer reaction. the best example is ATP. This option is also incorrect.
Option C
option C is correct because Acetic acid belongs to a group of organic compounds known as carboxylic acids. Carboxylic acid is characterized by the presence of carboxyl functional group (-COOH).
Conclusion
it is concluded that acetic acid contains carboxyl group.
~Hello
Fossils are one of the best evidence of evolution, mainly because they are the remains of living organisms from the past, which allow us to compare them with living organisms. However, the fossil record is notoriously incomplete and it is also biased in favor of animals with hard body parts, such as skeletons and shells. Soft bodied organisms and soft body parts are rarely preserved and there are often huge gaps in some evolutionary sequences. For example, Archaeopteryx is the earliest known bird, but it is already a bird, nothwithstanding some of the features that are unquestionably reptilian. The earliest known reptile with feathers is Longisquama, but there is a gap of some 75 million years between Longisquama and Archaeopteryx, and nothing has yet been found that are intermediate between these two important fossils.
Finally, DNA is virtually unobtainable from fossils, making it nearly impossible to compare the DNA of most fossils with living organisms. In terms of phylogenetic tree construction, DNA data is far superior to fossil evidence. However, if not for the existence of fossils, DNA data alone would be unconvincing as evidence of evolutionary change.

Hey there!
Alleles are different forms of the same gene that are always found on the same position of two homologous chromosomes. This means your answer is going to be option A.
Hope this helps.
Have a great day (:
A is direct variation because the line does not curve and x and y are in a direct ratio
