using jq how to sort array of object

There is an array of json object, using jq how to check if an object exists if so returns the true else false

I tried this but getting error

cat fruits.json | jq '.fruits[]| sort_by(.version)'

I would like to sort by decending order and output the price of the most recent version.

{"fruits": [        {"name": "banana","color": "yellow","price": 0.51,"version": 1        },        {"name": "banana","color": "yellow","price": 0.52,"version": 2        }    ]}
