Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): 'Swiss cheese' is characterised by the presence of large holes. Reason (R): The large holes are due to the production of a large amount of CO ₂ by a bacterium named Propionibacterium sharmanii. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).
- BBoth Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
- CAssertion (A) is true but Reason (R) is false.
- DAssertion (A) is false but Reason (R) is true.
Correct answer
B. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
Step-by-step solution
Assertion (A) is true because Swiss cheese is known for its characteristic large holes. Reason (R) is true because these large holes are formed due to the production of a large amount of CO ₂ gas by the bacterium Propionibacterium sharmanii during the ripening process. Since the production of CO ₂ by this specific bacterium is the direct cause of the large holes, Reason (R) is the correct explanation of Assertion (A). Answer: Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of As
