Concept:
This question tests the understanding of temporal adjectives (words describing time). Transient describes things that move or change quickly. The opposite must describe something that remains or endures for a significant duration.
Step 1: The definition of "TRANSIENT".
The word transient originates from the Latin transire (to go across). It describes something that lasts only for a short time; it is impermanent or fleeting. Example: "A transient feeling of joy."
Step 2: Identifying Synonyms.
• Brief: Refers to a short duration (Synonym).
• Momentary: Refers to something lasting only a moment (Synonym).
• Little: Usually refers to size, but in terms of time, it also implies a small amount.
Step 3: Selecting the permanent state.
The word "lasting" refers to something that continues to exist for a long time or is enduring. It is the direct opposite of a state that passes quickly. Thus, "lasting" is the correct antonym.
Final Answer: Option D
