By creating what, the vaccine provides resistivity ?

Options

A. Antigen
B. Antibodies
C. Germs
D. None of these

Explanation

To answer the question "By creating what, the vaccine provides resistivity?", we need to follow these steps:

### Step 1: Understand what a vaccine is
A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. It typically contains an agent that resembles a disease-causing microorganism.

### Step 2: Identify the components of a vaccine
Vaccines often contain weakened or killed forms of the microbe, its toxins, or one of its surface proteins. These components are intended to stimulate the immune system.

### Step 3: Determine the role of antigens and antibodies
- **Antigens** are substances that induce an immune response, typically found on the surface of pathogens.
- **Antibodies** are proteins produced by the immune system in response to antigens. They help to neutralize or eliminate pathogens.

### Step 4: Analyze the options
1. **Antigen**: While vaccines contain antigens to stimulate an immune response, they do not directly provide resistivity.
2. **Antibodies**: Vaccines lead to the production of antibodies in the body, which provide immunity and resistivity against diseases.
3. **Germs**: Germs are the pathogens that vaccines aim to protect against; they do not provide resistivity.
4. **None of these**: This option is incorrect as vaccines do provide resistivity through antibodies.

### Step 5: Conclusion
The correct answer is **B, antibodies**. Vaccines create antibodies in the body, which help to provide resistivity against diseases.
