Explanation:

• Question 8: CRISPR - Cas9 is a gene - editing technique. Its primary function is to cut DNA at targeted locations (option b). Modifying existing genes precisely (option a) is a consequence of cutting at targeted sites. Cloning entire organisms (option c) is not its primary focus. Inserting specific genes into DNA (option d) is part of genetic engineering but not the primary focus of CRISPR - Cas9's cutting function.
• Question 9: The human genome provides a complete set of genetic information necessary for development and function (option b). Intelligence (option a), height (option c), and immune system control (option d) are influenced by genes but are not the sole or primary function of the genome.
• Question 10: GMOs (Genetically Modified Organisms) have DNA altered in a non - natural way (option d). Their DNA is not altered naturally (option a). They are used in agriculture (option c) and not exclusively in human genetic engineering (option b).
• Question 11: CRISPR - Cas9 (option a) is the revolutionary gene - editing tool. Cloning (option b) is about creating identical organisms. Gene expression (option c) is about how genes are used to make proteins. DNA structure (option d) is about the physical form of DNA, not editing.
• Question 12: The primary concern in genetic testing privacy is the potential misuse of personal genetic information (option c). Availability of genetic therapies (option a), cost (option b), and accuracy (option d) are not privacy - related primary concerns.
• Question 13: Genetic engineering (option a) is the process of altering an organism's DNA to modify inherited traits. Inheritance (option b) is the passing of traits from parents to offspring. Gene editing (option c) is a part of genetic engineering. Gene expression (option d) is about gene function, not trait modification.
• Question 14: Recombinant DNA technology (option c) combines DNA from different sources. Cloning (option a) creates identical copies. Gene therapy (option b) is for treating genetic diseases. Gene editing (option d) is for modifying existing genes.
