Explanation:

The correct answer to the question is option 'A': Like a lizard. Birds are not capable of moving like lizards, as lizards can crawl and walk on branches, walls, and other surfaces using their limbs. Birds, on the other hand, have adapted to a different mode of movement - flying.

Reasoning:

Birds have wings that allow them to fly, unlike lizards or most other terrestrial animals. Flying is the primary mode of locomotion for birds, enabling them to cover long distances, reach different parts of trees or branches, and escape from predators.

Details:
Here are some details to further explain the reasoning behind the correct answer:

1. Bird Anatomy:
Birds have evolved with lightweight, hollow bones that reduce their overall weight and make them suitable for flight. They also possess feathers, which provide lift and control during flight.

2. Bird Flight:
Birds have strong pectoral muscles that power their wings, allowing them to generate lift and propel themselves through the air. They have a unique skeletal structure and wing shape that enables them to achieve lift and maneuverability.

3. Branch Navigation:
When birds need to move to the other side of a branch, they typically use their wings to lift off from the current position and fly over to the desired location. They have excellent control over their flight and can adjust their wing movements to navigate around obstacles and land precisely on the target spot.

4. Lizard Comparison:
Lizards, on the other hand, do not possess wings or the ability to fly. They rely on their limbs and specialized body structure to crawl, walk, or climb on various surfaces. Lizards use their limbs to grip onto branches or surfaces and move in a slow, creeping manner.

Conclusion:
In conclusion, birds do not move to the other side of a branch like a lizard. Instead, they use their wings to fly and navigate through the air. Flying is an essential adaptation for birds and enables them to access different parts of trees and escape from potential threats.
