Explanation (click to expand)

You should set the storage tier for the new blob to Cool. Cool storage is intended for data that is accessed infrequently and stored for 30 days or more. Cool storage has a similar time-to-access as Hot data. Although it has a slightly lower availability compared to Hot data, storage costs are lower.

You should not set the storage tier for the new blob to Archive. Although Archive storage is the least expensive, it also has several hours of retrieval latency.

You should not set the default storage tier for the account to Hot. Only the original blob in the storage account is accessed frequently. If the tier for the account is set to Hot, this applies to the new blob as well.

You should not set the default storage tier for the account to Cool. This is appropriate only for the new blob. If the tier for the account is set to Cool, this applies to the original blob as well.
