Question

Assertion (A): Yeast such as Saccharomyces cerevisiae is used in baking industry.

Reason (R): Carbon dioxide produced during fermentation causes bread dough to rise by thermal expansion.

विकल्प

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Assertion (A) is true but reason (R) is false.

Explanation:

Yeast is used in baking, so the assertion is true. The reason is false because fermentation-produced carbon dioxide makes the dough rise by forming bubbles; thermal expansion occurs later during baking.
