Answer:
The correct answer is B. "Suffering is eternal" is not one of the Four Noble Truths.
Explanation:
The Four Noble Truths are the fundamental norms of Buddhism left by Siddharta Gautama. After its enlightenment, the historic Buddha went to the north of India, to find its former masters, the five ascetics, who would now be their first disciples, and the first teaching that they gave him afterwards, leaving the samsara were the Four Noble Truths:
-Dukkha: all existence is impregnated with suffering, of pain, of frustration before the expiration of a constantly changing world. Everything is essentially fleeing.
-Samudaya: the origin of suffering is in the drive to live, in the desire for action, pleasure, possession.
-Nirodha: suffering is suppressed by annihilating the thirst for living, enjoyment, and acting. The radical extirpation of desires and passions leads us to absolute serenity and tranquility. It's nirvana
-Aria stanga marga: the path leading to nirvana is the noble path of the eight steps. Whoever follows it comes close to enlightenment.
