Step 1: Understand the question.
We must find which ocean is called the hearing pond. This nickname is about how well sound travels under that ocean's water.
Step 2: Recall how sound moves in water.
Sound travels faster and much farther in water than in air. Some oceans have the right depth and temperature to let sound carry across very long distances.
Step 3: Think about size and depth.
The largest and deepest ocean would give sound the most room to travel. The Pacific Ocean is the biggest and deepest ocean on Earth.
Step 4: Match the nickname.
Because sound can travel huge distances across it, the Pacific Ocean has been described as the hearing pond.
Step 5: Rule out the others.
The Atlantic, Antarctic, and Indian Oceans do not carry this nickname in the same way. So they are set aside.
Step 6: Match with the options.
The third option, Pacific Ocean, is correct.
\[ \boxed{\text{Pacific Ocean}} \]
