Assertion: Yeasts such as Saccharomyces cerevisiae are used in baking industry.
Reason: Carbon dioxide produced during fermentation causes bread dough to rise by thermal expansion.
(a) If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
(b) If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
(c) If Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(a) If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
Explanation:
Yeast is a fermentation agent. It is a known fact that yeast raises bread dough to rise and hence, yeast is also used to increase the volume, making the dough porous and the product soft. It is the carbon dioxide that is produced by the yeast that helps the dough to rise.
