Encryption is to Confidentiality as Vaccination is to:HealthMedicineImmunityDisease

To analyze the analogy presented in the question, we need to understand the relationship between the two pairs of terms.

1. Identify the First Pair:

   • The first pair is "Encryption" and "Confidentiality".
   • Encryption is a method used to ensure confidentiality by protecting information from unauthorized access.

2. Identify the Second Pair:

   • The second term needs to be related to "Vaccination".
   • We need to find a term that pertains to what vaccination achieves or protects against.

3. Analyze Possible Answers:

   • Health: Refers to overall wellbeing, not a specific outcome of vaccination.
   • Medicine: Refers to the field of healthcare and treatments, but is not a direct result of vaccination.
   • Immunity: Refers to the body's ability to resist a specific disease, which is a direct outcome of vaccination.
   • Disease: Refers to an illness, which is what vaccination seeks to prevent.

4. Determine the Best Answer:

   • Based on the analysis, "Immunity" is the most appropriate answer because just as encryption ensures confidentiality, vaccination ensures immunity against diseases.

Final Answer

Immunity is the term that best completes the analogy, since vaccination is specifically aimed at providing immunity to diseases.
