Hihi!
The correct answer would be a. Vaccines! This is because vaccines are an important and integral part of our society! And before I say anything further because I know people like to argue it and that's okay but vaccines don't cause autism or any other similar disorder. There is no evidence for this at all. In any case, when we're injected with vaccines we're given doses of antibodies so that our bodies would be prepared for that disease, because we have already seen the same particles in our vaccine, our body will know how to react in a proper and efficient way when it sees it in a "disease-like" form!
I hope I helped!

Pain signals move from peripheral nervous system to the spinal cord and many gates are present in between which regulate these signals. The slow pain signals then move from the spinal cord to the <span>hypothalamus and limbic system. The former releases hormones which are stress-related, the latter is associated with the emotions and feelings related to the same. These signals are slow because they pass through the brain parts which are responsible for the emotions also, which is limbic system and prefrontal cortex. This lag time enables the person to feel the severity of pain and protect from it. For example, the soldier feels less pain because he is attached to the war scenario in a different manner, as compared to the civilian, and therefore, pain signals follow a different pathway, leading to a feeling of comparatively lesser pain and other activities are less affected.</span>
