    The correct answer is option c) Deoxyribonucleic Acid.

    DNA stands for Deoxyribonucleic Acid. It is a complex molecule that contains genetic instructions for the development, function, and reproduction of all living organisms. It is composed of four different types of nucleotides: adenine (A), guanine (G), cytosine (C), and thymine (T), which are arranged in a specific sequence to encode genetic information.

    Option a) Double-stranded Nucleic Acid and option d) Double-helix Nucleic Acid are incorrect because they refer to the physical structure of DNA, which is double-stranded and has a helical shape. These options describe the physical properties of DNA, but not its name.

    Option b) Ribonucleic acid is another type of nucleic acid that is similar to DNA, but it differs in its chemical structure and function. RNA contains ribose sugar instead of deoxyribose sugar found in DNA, and it uses uracil (U) instead of thymine (T) as one of its nucleotides. RNA has several important functions in protein synthesis and gene regulation.

    In summary, DNA stands for Deoxyribonucleic Acid, and it is a complex molecule that contains genetic information for all living organisms.
