The right answer is: vitamin C and choline
Choline (vitamin B4) is the precursor on the one hand acetylcholine (important neurotransmitter and neuromodulator) and on the other hand, the cascade initiated by betaine (intermediate in the biological methylation and precursor of membrane lipids). In this, it is considered, by extension, as an integral part of the family of B vitamins,
Vitamin C protects against cellular aging, is essential for the immune defenses and increases the assimilation of iron of plant origin. It also contributes to the formation of collagen. Its deficiency leads to a disease called scurvy (hence the ascorbic acid name of vitamin C).
Answer: A. Peaceful protests
Explanation:
You included no text and neither did you reference one but this should be the correct answer.
Martin Luther King Jr. was known for his non-violent style of protests that would ensure that the government would not use any violence that ensues as pretext to shutdown the protest.
In organizing peaceful protests, King made civil rights marches and the movement in general more effective because they would stage longer protests that the government would have little justification for shutting down. It also drew more empathy from people for the movement who listened to the message and not the violence.
<span>It is going to depend on what you consider stable. A
diverse population would be more resistant to disease because of simple
biology. The more sources for possible resistance the better the

in to consideration things like the availability of modern medicine and
the ability to be isolated during illness. </span><span>
Personally I think it has to do with the fact that many of the worlds
more diverse population centers are also many of the worlds largest
population centers which make them less prone to invasion on that basis
alone. </span>
