From the given options, select the most appropriate word to fill in the blank in the given sentence:-

Her new book was wonderfully ____ of the long forgotten memories of bygone times. 

evocative

The correct answer is Option (2) → evocative

The completed sentence is: Her new book was wonderfully evocative of the long forgotten memories of bygone times.

Evocative (Adjective): Bringing strong images, memories, or feelings to mind. Since the book is described as wonderfully doing this for "long forgotten memories," evocative is the perfect fit. 

Why the Other Options are Incorrect:

Evasive (Adjective): Tending to avoid commitment or self-revelation; not direct. (Does not fit the positive context of bringing back memories).

Contextual (Adjective): Relating to or depending on the context. (Does not fit the emotional/memory-recall context).

Obnoxious (Adjective): Extremely unpleasant or offensive. (Does not fit the positive modifier "wonderfully").
