Select the most appropriate ANTONYM of the given word.
Oral

The correct option is Inscribed.

Let us analyze the meaning of the given word and find its opposite from the options provided:

1. Oral: Relates to speech or spoken words rather than written communication (e.g., an oral presentation).
2. Inscribed: Means written, carved, or engraved on a surface (such as stone, metal, or paper) to keep a permanent record. Since oral communication is spoken and unwritten, "inscribed" represents communication that is written down, making it the direct antonym.

Let us also look at the other options:
- Verbal: Relating to or in the form of words, frequently used to mean spoken. This is a synonym rather than an antonym.
- Obligatory: Mandatory or compulsory; required by a rule or law. It is unrelated to speech or writing.
- Dejected: Sad, depressed, or downcast. It is completely unrelated to the given word.

Thus, Inscribed is the most appropriate antonym for Oral.
