Aray is a defined term because it

a) has no width or depth
b) is described using an undefined term
c) has no informal definition
d) travels forever in one direction

A ray is a defined term we have to give the reason of the above statement.

A ray is a line or a part of a line that has one endpoint which we defined and other goes on infinitely in only one direction.

One of the example is a sun's ray of light in space. Light from the sun originates and travels from the sun, and its path extends infinitely.\

Hence, we say that "A ray is a defined term because it travels forever in one direction"

Option D is correct.
