AIIMS 2017 Botany Microbes in Industrial Products Assertion Reason Question
Assertion: Besides curdling of milk, LAB also improve its nutritional quality, by increasing vitamin – B₁₂. Reason: LAB check disease causing microbes when it is present in human stomach.
Both Assertion and Reason are true and Reason is the correct explanation of Assertion
Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
Assertion is true but Reason is false
Both Assertion and Reason are false
Correct Answer
Detailed Explanation
Option D is correct because the assertion that lactic acid bacteria (LAB) improve the nutritional quality of milk by increasing vitamin B₁₂ is false; LAB primarily produce lactic acid and are not significant sources of vitamin B₁₂. Additionally, while LAB can inhibit some pathogenic microbes in the gastrointestinal tract, this does not directly relate to the assertion about nutritional quality. Therefore, both the assertion and reason are false. Options A and B are incorrect because they incorrectly state that either the assertion or reason is true, while option C is incorrect as it suggests the assertion is true when it is not.
