• A. luminous body
• B. non-luminous body
• C. reflecting body
• D. transparent body

Answer 1

The correct option is A luminous body

Objects which emit light of their own are called luminous objects. Stars, flashlight, and candles, etc. are examples of luminous objects. Non-luminous objects are visible because they reflect light emitted by luminous objects. A transparent body is one that allows light to easily pass through it.
