Explanation:

Regular exercise in the second trimester of pregnancy has multiple benefits. Relieving backaches (due to postural changes and muscle support), developing stamina for labor (as labor requires physical endurance), and protecting joints (by maintaining joint health and flexibility) are all valid benefits. So "All of the choices are correct" is the right option.
