If the Assertion is correct but Reason is incorrect.

(C) The Assertion is correct because $Saccharomyces \text{ } cerevisiae$ (brewer's yeast) is widely used in the baking industry to leaven bread dough.The Reason is incorrect because the rising of bread dough is caused by the trapping of $CO_2$ gas bubbles produced during fermentation within the dough matrix, not by thermal expansion. While heat during baking does expand the gases, the primary mechanism for the 'rising' (leavening) of the dough is the metabolic activity of yeast producing $CO_2$.

Three rods of equal length $l$ are joined to form an equilateral triangle $PQR.$ $O$ is the midpoint of $PQ.$ The distance $OR$ remains the same for a small change in temperature. The coefficient of linear expansion for $PR$ and $RQ$ is the same,i.e.,$\alpha_2,$ but that for $PQ$ is $\alpha_1.$ Then the relation between $\alpha_1$ and $\alpha_2$ is:
