Answer 1

Hint: An individual may be exposed to an antigen to induce immune responses, a type of immunity known as active or artificial immunity. The material used to induce artificial active immunity, the antigen or a mixture of antigens, is known as a vaccine (or an immunogen), the process of generating such an immune response is called immunization.

Complete step-by-step answer:
Hepatitis is caused by a virus so it is a viral disease. There are two subgroups i.e., hepatitis type A virus (HAV) and hepatitis type B virus (HBV). HBV causes serum hepatitis, it is mostly transmitted by blood or blood-contaminated instruments. Hence only adults are susceptible to HBV and vaccines are available for the same. But children and young adults are susceptible to HAV, no vaccines are available.
Gonorrhea is caused by a bacteria Neisseria ionorrhoeae, it is a sexually transmitted disease. Its symptoms include urethral discharge of yellow creamy pus in males and frequent painful urination with a burning sensation in females vaginal discharge. Drugs used to treat gonorrhea are:- Penicillin G plus probencid, Ampicillin plus probencid ceftraxone plus doxycycline.
Syphilis is also caused by bacteria, it is also a sexually transmitted disease. Its symptoms include small, painless, reddened ulcers, skin rash, loss of hair patches, malaises, and fever. Drugs for treatment are Benzathine and Penicillin G.
AIDS is a viral disease caused by the human immune deficiency virus, it is sexually transmitted, through contact with transmitted blood, vaginal fluids semen, and infected breast milk. No cure exists for AIDS.


Therefore the correct answer is Option B.

Note: The centers for disease control and prevention(CDC) recommends vaccinations from birth through adulthood to provide a lifetime of protection against many diseases and infections, such as influenza, pneumococcal disease, human papillomavirus, measles, and hepatitis A and B.
