Radial symmetry is advantageous to sedentary organisms because sensory receptors are evenly distributed around the body. For sessile (sedentary) organisms, radial symmetry is useful because the animal can just "sit down" and grab food or detect threats from all directions.

Radial symmetry in animals and its advantages
Assertion: Radial symmetry in animals is advantageous in detecting food and danger.
Reason: It allows the animal to be able to respond to stimulus from any direction.
Explanation:
Radial symmetry is a type of symmetry where an organism can be divided into similar halves by more than two planes passing through a central axis. This type of symmetry is commonly seen in jellyfish, sea anemones, and starfish.
Advantages of radial symmetry in animals:
1. Detecting food:
Radial symmetry allows an animal to detect food from any direction. The presence of sensory cells on the tentacles or arms of starfish or sea anemones helps them detect food particles in the water from any direction.
2. Detecting danger:
Radial symmetry also helps animals detect danger from any direction. For example, a sea anemone can detect the presence of a predator from any direction and immediately retract its tentacles and close its mouth.
3. Efficient movement:
Radial symmetry also allows animals to move in any direction efficiently. For instance, starfish use their arms to move in any direction, giving them the advantage of escaping from predators or reaching food quickly.
Reasoning of the Assertion:
Radial symmetry allows animals to detect food and danger from any direction, which is advantageous for their survival.
Hence, both the assertion and reason are true, and the reason is the correct explanation of the assertion. Therefore, the correct answer is option A.
