Answer
BTherefore, the correct answer is Option B. Total lung capacity is the maximum amount of air maximal inspiratory effort can held in the Jurassic. Hence, total lung capacity equals option B 'Maximum amount of air contained in the lungs after a maximum inspiratory effort.'
Explanation
## Step1: The term "Total Lung Capacity" refers to the overall volume of the lungs, which is the maximum amount of air the lungs can contain. This included the volume of air inhaled during the deepest possible breath and the volume of air that remains in the lungs even after a maximal forcefully exhale.## Step 2: Looking at all provided options and relating them to the definition obtained from step 1, we could discard some choices. Option A refers to a single breath, which would be equivalent to tidal volume rather than total lung capacity. Option C refers to the residual volume, the air still left in the lungs after a full exhalation, which is just a part of the total lung capacity. ## Step 3:Comparing the definition with Options B, and D, option D includes the air volume when the deepest possible inhalation and most forced exhalation are done, and option B refers to the fullest amount of air a lung can hold- which fits the definition fully.
