To solve this question, we need to match each disease with its correct type of vaccine. Understanding the different types of vaccines and their applications is crucial for this task.
- Types of Vaccines:
- Inactivated Vaccines (i): Contain killed versions of the germ that causes a disease.
- Subunit, Recombinant, Polysaccharide, and Conjugate Vaccines (ii): Use specific pieces of the germ.
- Toxoid Vaccines (iii): Use a toxin made by the germ that causes a disease.
- Live Attenuated Vaccines (iv): Contain a living but weakened form of the germ.
- Matching Diseases with Vaccine Types:
- Example Disease A: Matches with (iv) Live Attenuated Vaccines. Many vaccines for viruses use this type as it helps create a long-lasting immune response.
- Example Disease B: Matches with (iii) Toxoid Vaccines as it is typically created for diseases caused by bacterial toxins.
- Example Disease C: Matches with (ii) Subunit, Recombinant, Polysaccharide, and Conjugate Vaccines, used for targeting specific parts of pathogens.
- Example Disease D: Matches with (i) Inactivated Vaccines, common for diseases where live vaccines are not suitable.
Based on this understanding, the correct match is:
A-(iv), B-(iii), C-(ii), D-(i).
Therefore, the correct answer option is A-(iv), B-(iii), C-(ii), D-(i).
