Requesting clarification on the following question

First of all, thank you for the explanation. I have a bit of confusion. I cannot seem to imagine the document structure differently for option B and C. What I am thinking is like this for both options,

{
  "_id": ObjectId("customer_id"),
  "name": "Customer Name",
  "contactInfo": "Contact Information",
  "accountInfo": "Account Information",
  "transactions": [
    {
      "_id": ObjectId("transaction_id"),
      "amount": 100.00,
      "date": ISODate("2023-01-01T00:00:00Z"),
      // Other transaction-related fields
    },
    // Additional transactions
  ]
}

Can you please give me the one example for option B and C according to your understanding?

I see. However, won’t there be a possibility of the transactions array going out of bound? Considering that, option A seems best to me. Can you please explain this?

Thank you for your kind response and time.
