A teacher presents information by accessing it from e-learning portals while displaying confidence in the domain of the concerned knowledge. This may involve which of the following?

Presenting information taken from e-learning portals as one's own confident knowledge may involve non-observance of ethicality.

Using others' content without acknowledgement raises questions of academic honesty and plagiarism.

Inappropriate information coverage would concern wrong or insufficient content, not this situation.

Lack of harmony and relevance would mean content that does not fit the topic, which is not implied.

Lack of technical skill would show inability to use the technology, but the teacher uses it confidently.

Ethical practice requires citing sources and honestly representing the origin of knowledge.
