Incorrect Statements Given by the Teacher:
Sodium Chloride Prevents Microbial Infection in Food:
- This statement is incorrect because sodium chloride, commonly known as table salt, is used as a preservative in food to enhance flavor and extend shelf life, but it does not prevent microbial infection. Other methods such as proper cooking, refrigeration, or using chemical preservatives are typically used to prevent microbial contamination in food.
Rhizobium May be Called Beneficial Bacteria:
- This statement is correct. Rhizobium is a type of beneficial bacteria that forms a symbiotic relationship with leguminous plants, such as peas and beans, by fixing nitrogen from the atmosphere into a form that plants can use for growth.
Vectors are the Agents for Killing the Microbes:
- This statement is incorrect. Vectors are organisms such as mosquitoes, ticks, and flies that can transmit diseases from one host to another, but they are not agents for killing microbes. In fact, vectors can often harbor and spread harmful microbes, increasing the risk of disease transmission.
Therefore, the correct answer is option 'C' - "Vectors are the agents for killing the microbes."
