Which of the following are barriers to acceptance of communicated messages?

Barriers to the acceptance of communicated messages include the attitude of the listener, the values of the decoder and status clash, so statements 2, 3 and 4 hold.

Statement 2 is right because a hostile or resistant listener attitude blocks a message from being accepted.

Statement 3 is right because the decoder's own values filter and can reject a message that conflicts with them.

Statement 4 is right because a clash of status between communicators breeds mistrust and hampers acceptance.

Body language with positive vibes in statement 1 aids rather than hinders acceptance, so it is not a barrier.

Knowledge stimuli in statement 5 support understanding and reception, again the opposite of a barrier.

Acceptance barriers act at the receiver's end, where attitude, values and perceived status decide whether the message is taken in.
