Question

are luminous objects sources or receivers of light? receivers sources

Explanation:

Luminous objects are defined as objects that produce their own light. For example, the sun (shown in the image) is a luminous object and is a source of light. Receivers of light would be objects that reflect or absorb light from other sources (like the moon, which reflects sunlight). So luminous objects are sources of light.

Answer:

B. SOURCES (assuming the options are labeled with "RECEIVERS" as one and "SOURCES" as the correct one; if the options were A. RECEIVERS, B. SOURCES, then the answer is B. SOURCES)
