Which of the following describes something that is needlessly repetitive?

The term "redundant" specifically refers to something that is unnecessarily repetitive or superfluous. In various contexts, such as writing or speech, redundancy indicates the inclusion of information that is repeated or overly wordy, which can detract from clarity and efficiency.

For example, in communication, one might say, "I personally believe" instead of simply saying "I believe." The phrase "personally" creates redundancy, as the act of believing is inherently personal.

The other options provided do not convey the same meaning. "Reply" refers to a response to a question or comment, "res judicata" is a legal doctrine concerning the finality of judgments, and "redress" pertains to remedying a situation or correcting a wrong. None of these terms imply needless repetition. Thus, "redundant" is the most fitting term to describe something that is needlessly repetitive.
