Exam CBSA topic 1 question 189 discussion

Actual exam question from Blockchain's CBSA

Question #: 189
Topic #: 1

[All CBSA Questions]

Consider the following scenario: A large department store chain is being pressured by lawmakers to provide evidence that proves the store's clothing is not produced through child labor. This is no easy task currently due to the store's clothing being transferred between at least 6 different parties in between creation and placement at the storefront. The store chain is considering the use of blockchain to solve their problem. Discretion in the reading and writing of transactions is highly important to the store chain to protect its proprietary interests.
Which solution would best solve the product need?

A. Use a public blockchain that supports assets, then create a new clothing asset for each item created. When the clothing item is transferred to the next party in the process, require that the associated blockchain asset be transferred to the next party's blockchain account with relevant metadata. The lawmakers can now view the transactions and transfers at any time.
B. Use a permissioned blockchain to build the technology. Require every party involved in the process to host a node on you network. Create a new clothing asset for each item created. When the clothing item is transferred to the next party in the process, have the previous party use your web portal to initialize a chaincode Smart Contract to transfer control of the asset. When the next party receives the asset have them use your web portal to initialize a chaincode Smart Contracts to acknowledge receipt of the asset. Provide read-only permissions to the lawmakers so they can receive the evidence they are looking for.
C. Both options are equally suitable
D. None of the above

As the content of the public blockchain is totally open and because of "discretion of reading and writing transactions", I think the answer is B
