Option C could work, but setting the consistency level to strong doesn't really solve the ACID requirement. A is the way to go.

Option B might be tempting, but it won't give you the ACID guarantees you need. Go with A to ensure data integrity.

I agree with Leonida. Option A is the best choice here. Performing a batch operation is the most efficient way to update the documents.

I think we should update the document of each family member by using a transactional batch operation. It ensures atomicity and consistency.
