Which of the following is an example of the self luminous body?A) SunB) MoonC) Electric bulbD) Earth

Answer: (A) Sun
Explanation:
A self-luminous body is one that generates and emits its own light due to internal energy sources, such as nuclear fusion, chemical reactions, or electrical processes. Let us analyze each option:
(A) Sun:
• The Sun is a self-luminous body because it produces its own light through nuclear fusion reactions occurring in its core.
• These reactions release an immense amount of energy in the form of light and heat, making the Sun the primary source of light for our solar system.
• Correct Answer: The Sun is self-luminous.
(B) Moon:
• The Moon is not self-luminous; it does not produce its own light.
• Instead, it reflects the light emitted by the Sun, which is why we can see the Moon at night.
• Incorrect Answer.
(C) Electric Bulb:
• An electric bulb is not self-luminous in the natural sense. It emits light when electricity flows through its filament or gas, but it relies on an external energy source (electricity).
• Incorrect Answer.
(D) Earth:
• The Earth is not self-luminous; it does not produce its own light. Like the Moon, it reflects light from the Sun.
• Incorrect Answer.
The Sun is an example of a self-luminous body. Thus, the correct option is:
