• D. Designed Sound is sound that is totally created from scratch in a studio environment.

Answer: (D)

Designed sound means sounds that are created from scratch in a studio environment rather than recorded from real-world sources. This exact idea is what the statement is capturing: the sound is fully crafted in the studio, giving the designer complete control over its character and timing. The other descriptions mix up concepts—one talks about using everyday sounds recorded or reproduced in post, which relies on existing sources rather than original creation; another mentions copyright licensing, which is about legal use rather than how the sound is produced; and another repeats the studio-creation idea but uses different terminology that isn’t the standard definition of designed sound. In practice, designers build these sounds through synthesis, manipulation, or Foley techniques, all inside the studio, to produce something that didn’t exist before.
