Answer:
The structure of the DNA is ideal for the complex function that it plays.
Some of the features of the structure of all DNA molecules are:
<em>Sugar- phosphate backbone:</em>
The sugar- phosphate backbone is ideal for providing the DNA a ladder- like shape which is essential for its functions.
<em>Hydrogen bonds:</em>
The hydrogen bonds present in the nucleotides keep both the DNA strands intact. If the hydrogen bonds were not present then the double helix would not have been able to form.

D. A hurricane carries ocean water across the coast and damages houses of people.
Explanation:
This question is looking for a statement that shows the interaction of an atmosphere, hydrosphere and biosphere. Firstly, atmosphere refers to the layer of the air that surrounds the earth i.e it pertains to air. Hydrosphere refers to the part of the earth occupied by water bodies e.g sea, river, ocean etc. i.e. it pertains to water.
Biosphere is the part of the earth that has to do with life i.e. it pertains to living organisms e.g plant, animal, human etc.
Based on the definition of each component, option D truly shows the relationship/interaction of the three components mentioned. That is, A hurricane (represent part of the atmosphere because it has to do with air) carries ocean water (represents hydrosphere because it involves water body) across the coast and damages houses of people (represents biosphere because it talks about living humans).
