The Four Noble Truths in Buddhism state that human life is filled with suffering, that suffering is caused by desire, and that suffering will stop when one learns to suppress desire, and the way to suppress desire is by following the Eightfold Path. Option D is correct.
Following the Noble Eightfold Path leads to liberation in the form of nirvana. It constitutes an early summary of the path of Buddhist practices which result in liberation from samsara, the painful cycle of rebirth.
It consists of eight practices: right view, right resolve, right speech, right conduct, right livelihood, right effort, right mindfulness, and right samadh.
