What is a caution to consider when performing Urdhva Dhanurasana (Upward Facing Bow Pose)?

The correct choice highlights a significant consideration when practicing Urdhva Dhanurasana, particularly in later stages of pregnancy. In this advanced backbend, the body engages in a deep extension of the spine and opens the hips, which can place considerable strain on the abdominal region and the lower back. For individuals in late stages of pregnancy, there is an increased risk of discomfort and injury due to the physical changes that occur, such as the shift in center of gravity, hormonal changes affecting ligament stability, and abdominal pressure.

Practicing this pose can also challenge balance and body awareness, potentially leading to falls or ineffective alignment. Therefore, it is generally advisable for those in late stages of pregnancy to avoid this pose or modify it significantly to ensure safety and comfort for both the individual and the baby.

The other options, while they may be important to consider in other contexts, do not specifically address the unique physiological changes and risks involved in late pregnancy as they relate to the demands of Urdhva Dhanurasana.
