According to Buddhist philosophy, the world is _______ (anicca).

Transient

The correct answer is Option (3) → Transient

"According to Buddhist philosophy, the world is transient (anicca) and constantly changing; it is also soulless (anatta) as there is nothing permanent or eternal in it. Within this transient world, sorrow (dukkha) is intrinsic to human existence. It is by following the path of moderation between severe penance and self-indulgence that human beings can rise above these worldly troubles. In the earliest forms of Buddhism, whether or not god existed was irrelevant.".
