Concept:
Surya Namaskar (Sun Salutation) is a sequence of 12 powerful yoga asanas that provides a great cardiovascular workout and is a complete body workout.
Step 1: Identifying asanas in the sequence.
The traditional 12-step sequence includes:
1. Pranamasana, 2. Hasta Utthanasana (A), 3. Padahastasana, 4. Ashwa Sanchalanasana (C), 5. Parvatasana (or Dandasana), 6. Ashtanga Namaskara, 7. Bhujangasana (D), 8. Parvatasana, 9. Ashwa Sanchalanasana, 10. Padahastasana, 11. Hasta Utthanasana, 12. Pranamasana.
Step 2: Excluding non-members.
Simhasana (Lion Pose) and Garudasana (Eagle Pose) are independent asanas and are not part of the standard Surya Namaskar sequence. Therefore, only A, C, and D are correct.
