Watson and Crick's model explained mutability because bases pairs can suffer changes (mutations) during DNA replication. Moreover, this model also explained stability because DNA strands are held together by hydrogen bonds.
Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.
In Watson and Crick's model, both DNA strands are held together by hydrogen bonds between nitrogenous bases on opposite DNA strands, thereby providing stability to the DNA molecule.
In DNA, Guanine always pairs with Cytosine by three hydrogen bonds, while Adenine always pairs with Thymine by two hydrogen bonds.
Moreover, Watson and Crick suggested that mutations could occur as a consequence of a base occurring very infrequently in one of the less likely tautomeric forms during DNA replication, thereby also explaining the mutability of life.

Answer:
C. Angiosperms and Conifers
<em><u>Angiosperms:</u></em>
<em>A plant that has flowers and produces seeds enclosed within a carpel. The angiosperms are a large group and include herbaceous plants, shrubs, grasses, and most trees.</em>
<u><em>Conifers:</em></u>
<em>A tree that bears cones and needle-like or scale-like leaves that are typically evergreen. Conifers are of major importance as the source of softwood, and also supply resins and turpentine.</em>
Hope this helps you out! Took some time to do this, maybe a brainliest? Sorry for asking! Have a good day!!
<em>Lets take a look at all the choices:</em>
A) Energy utilization
All organisms require energy to survive. That question is out for sure!
B) Complex Yet Organized
All living organisms are complex, and if they weren't organized, well, they wouldn't exist or they would have some serious problems!
C) Capable of Self-Reproduction
Simple: Not all organisms are able to reproduce asexually, for example, humans. We do not reproduce asexually. Therefore it is not a characteristic of <u>ALL</u> living organisms
D) Composed of Multiple Cells
No-brainer! All living organisms are composed of multiple cells!!!!!!!!!!!!
Therefore, the answer is C) Capable of Self-Reproduction
