Which of the following documents are required to be held in their original and physical form?

Trust deeds and contracts must be held in their original and physical form due to their legal significance and the requirements often outlined in relevant laws or regulations. These documents typically define the rights and obligations of parties involved, and keeping them in their original form ensures their legal enforceability and authenticity. In many jurisdictions, original signatures are necessary to validate these documents, and retaining them in physical form helps to avoid disputes regarding their validity.

Other types of documents, while important, may have different requirements concerning preservation. For example, trade order tickets and physical contract notes can often be archived electronically, as regulatory bodies may accept digital records provided they meet specific standards for preservation and accuracy. Similarly, shareholder agreements may not have the same strict original form requirements, allowing for more flexible storage and documentation practices. Thus, the emphasis on the original and physical format of trust deeds and contracts arises from their critical legal implications, making option C the correct choice.
