Which of the following is an example of physical barrier to communication?

Ill health is a physical barrier to communication, since a sick or fatigued body dulls attention and weakens both sending and receiving of messages.

Physical barriers arise from bodily and environmental conditions such as sleeplessness, poor health, noise, distance and drug effects that impede the channel.

Cultural disparity is a socio cultural barrier rooted in differing values and customs, not a bodily condition.

Inattention is a psychological barrier, a state of mind that lets the message slip rather than a physical obstacle.

Verbalism, the empty use of words without shared meaning, is a semantic or language barrier, not a physical one.

Subjective stress, including ill health, is classed among physical barriers alongside competing stimulus and environmental stress.
