In a social poster what idea can large eyes and a closed mouth express?

Seeing everything but being unable to speak

The governing concept is visual symbolism in social communication. In a poster, a feature may be enlarged or simplified so that it carries an idea beyond literal appearance. Large eyes can suggest awareness, witnessing, or seeing injustice, while a closed mouth can suggest silence, censorship, fear, or lack of power. Together they can communicate the condition of people who observe a problem but cannot speak openly about it, so option A is correct. Option B treats the image as a scientific lesson rather than a symbol; C describes measurement, not communication; and D is too narrow because the combination can convey a serious social message. The exact meaning depends on the surrounding text and imagery, but the proposed interpretation is the most coherent.
