Answer:b

Explanation:

From the question, the stoichiometry of the balanced reaction equation showed that 180gof glucose give 134.4L of CO2. Then we are given to find the volume of carbon IV oxide given off by 126g of glucose. This is done as shown in the image by relating what is given to the stoichiometry of the balanced reaction equation to obtain the answer as shown.
