Answer: (B)

Verified step by step guidance

1. Understand the difference between active and passive immunity: Active immunity involves the body producing its own antibodies in response to an antigen, while passive immunity involves receiving antibodies from an external source.
2. Recognize the difference between natural and artificial immunity: Natural immunity occurs through natural exposure to pathogens, whereas artificial immunity is induced through medical interventions like vaccines or antibody injections.
3. Analyze vaccination: Vaccination introduces a harmless form or component of a pathogen to stimulate the immune system without causing disease, prompting the body to produce its own antibodies.
4. Combine the concepts: Since vaccination causes the body to actively produce antibodies (active) and is done through a medical procedure (artificial), vaccination stimulates active artificial immunity.
5. Therefore, the correct completion of the sentence 'Vaccination stimulates __________ immunity.' is 'active artificial'.
