Step 1: Analyzing the Classical Base of Yog Mudra:
Yog Mudra (or Yoga Mudrasana) traditionally requires a foundational seated posture that locks the lower body securely to allow a deep forward bend without lifting the hips. This base is typically Padmasana (Lotus Pose).
Step 2: Analyzing Upper Body Mechanics:
In this posture, the hands are brought behind the back, where one hand clasps the opposite wrist. The practitioner then exhales, flexes from the hip joints, extends the spine forward, and brings the forehead or chin down to touch the floor.
Step 3: Finding the Exact Match:
Option (B) accurately specifies both the foundational cross-legged posture (Padmasana) and the correct rear wrist clasp alignment.
