Answer:
B) physiological
Explanation:
When we feel under pressure, our nervous system instructs the body to release stress hormones, such as adrenaline and cortisol, that produce <u>physiological changes</u> in order to help us cope with the threat or danger we see looming over us. It is what is called "stress response" or "fight or flight" reaction.
When we are stressed, the respiratory system suffers the effect immediately. It usually costs us more to breathe and we do it faster in an attempt to quickly bring oxygen-rich blood to the body.
Cardiovascular effects also occur. When the stress is acute (at that precise moment), the heart rate and blood pressure rise, but return to normal once this has passed. If acute stress is experienced repeatedly or if the stress becomes chronic (if it lasts for a long period of time), it can cause damage to the veins and arteries. <u>This increases the risk of hypertension, heart attacks or heart attacks</u>.

Dutch carrot farmers started growing the new orange carrots in honor of William of Orange, and the traditional, more colorful carrots, were tossed aside for these newly fashionable orange carrots."
</em>
The discovery of new lands with settlers bringing their traditions spread the farming of orange carrots instead, across the world.
<em>
</em>And happily ever after, we now associate carrots with:
<em>Orange!</em><em>
