Suggested Answer:
Azure storage offers different access tiers: hot, cool and archive.
The archive access tier has the lowest storage cost. But it has higher data retrieval costs compared to the hot and cool tiers. Data in the archive tier can take several hours to retrieve.
While a blob is in archive storage, the blob data is offline and can't be read, overwritten, or modified. To read or download a blob in archive, you must first rehydrate it to an online tier.
Example usage scenarios for the archive access tier include:
✑ Long-term backup, secondary backup, and archival datasets
✑ Original (raw) data that must be preserved, even after it has been processed into final usable form.
✑ Compliance and archival data that needs to be stored for a long time and is hardly ever accessed.

"rehydrated" is a funny term. I imagine that archived data are like "mummified" data - hidden for a very long time, dehydrated, and in order to recognize it, you "rehydrate" it.

The way I guessed about it is that we talk about Data Lake for large data usage, so it should be something related to water so that it becomes accessible- hence 'rehydrated'..

The answer is correct. Be aware though that rehydrating increases the costs, tradeoff for the Archive tier, which is usually the cheapest.

D. must be rehydrated before the data can be accessed. The Archive access tier of an Azure Storage Account is designed for storing data that is infrequently accessed and for which retrieval times of several hours are acceptable. Data in the Archive access tier is stored in a secure, durable, and highly available manner, but it is not immediately accessible. In order to access data in the Archive access tier, it must first be "rehydrated," which is a process that retrieves the data from storage and makes it available for access. Rehydration typically takes several hours to complete, and once the data is rehydrated, it can be accessed just like any other data in the storage account.

While a blob is in the Archive tier, it can't be read or modified. To read or download a blob in the Archive tier, you must first rehydrate it to an online tier, either Hot or Cool. Data in the Archive tier can take up to 15 hours to rehydrate, depending on the priority you specify for the rehydration operation. For more information about blob rehydration, see Overview of blob rehydration from the Archive tier.
