Suggested Answer: A

In Hyperledger Fabric, a range query with a start and end key is a type of query that searches for all ledger entries whose keys fall within the specified range defined by the startKey and endKey. This is used, for example, to retrieve a subset of assets from the ledger based on their key values, effectively iterating over a specified range .

A) seems like the correct answer. I've used range queries to fetch all the data between a start and end key. Handy for fetching data in batches.

I disagree with option C, I believe option A is more accurate as it directly mentions searching for keys within a range.
