Answer:
c. fear
Step-by-step explanation:
Assuming these options:
a. boredom
By definition boredom is "the state of being weary and restless through lack of interest the boredom of a long car trip" and this can't be a emotion easy to identify in any culture since depends of the culture, and is not masifested on facial expressions always.
b. resignation
The resignation by definition is "the acceptance of something undesirable but inevitable" and is not always present by a facial expression, so that's not correct.
c. fear
By definition the fear is "an unpleasant emotion caused by the threat of danger, pain, or harm". And is an emotion that can be percibed on any culture since the facial expression is very different from the other emotions.
d. frustration
Some people in some cultures not express the frustration with a facial expression. So then this is not the correct option
