   A cloud storage provider wants to protect customer data against the failure of multiple disks in a distributed storage cluster. They are considering using erasure coding with a 10/16 configuration (10 data fragments, 6 parity fragments). What is the primary benefit of this approach compared to storing three full replicas of each object?

   • AIt provides better fault tolerance because it can tolerate up to 6 disk failures.
   • BIt reduces storage overhead while still providing high durability.
   • CIt eliminates the need for backups because the data is already redundant.
   • DIt simplifies data recovery because fragments are independent and can be read in parallel.
