Step 1: Recall the facts:
Translate the word. Simha in Sanskrit is lion.
Step 2: Match the facts with the options:
Option (1): The word simha itself means lion, and the open-mouth, tongue-out face shows the roar. This matches.
Option (2): Cobra belongs to Bhujangasana, so it is not the answer.
Option (3): Rabbit belongs to Shashankasana, so it is not the answer.
Option (4): Frog belongs to Mandukasana, so it is not the answer.
Step 3: Decide:
The name of the pose gives the answer directly, and the other animals belong to other asanas.
Final Answer:
Option (1) is correct. \[\boxed{\text{Lion}}\]
