Explanation:

The text states that during the return hike, Sahana and Raj were busy finding imaginary creatures (a crown-shaped puddle, goblin-like rock, etc.). When people are engaged and having fun, time often feels like it passes quickly, which matches why the hike felt short. The other options are not supported by the text: there's no mention of racing to forget Dragon Mountain, the path being downhill, or the family being lost.

Answer:

She is having so much fun spotting imaginary creatures that time passes quickly.
