You can often tell what a word means by its context in a sentence.
Context can help a lot when you don't understand what a certain word means, so depending on it, it can mean one thing or another.
From the excerpt presented, it is obvious that the narrator is uncomfortable. The most obvious sentence to prove this is <u>B - My posture is consciously congruent to the shape of my hard chair. </u>The person, writing in first person, is conscious of his or her discomfort, we can gather this from this sentence. They describe their chair as hard, and is accomodated to this uncomfortable chair. This sentiment is painfully relatable. The chair is rigid and so is the posture of this person, because there's no other option but to sit in the hard chair.
