Explanation: A. On Training record, the Student Lookup field can be made optional. Lookup fields can be configured as optional, meaning the user can leave the field blank if no student is associated with the training session. C. On Training record, users can only delete Students, if they have access to it. Since a Lookup relationship does not enforce ownership, Why the other options are incorrect: B. On Student record, users can set up Roll-up summary field on Training records. Roll-up summary fields are only available on Master-Detail relationships, not Lookup relationships. In a Lookup relationship, users cannot create roll-up summary fields, so this statement is incorrect. D. Cross-object field updates between Training and Student records are not supported. This statement is incorrect because cross-object field updates are supported, especially if you are working with a Lookup relationship or a Master-Detail relationship. However, the specifics of the update process depend on the field type and the context in which the update is triggered.
A is right lookup fields can be optional. D is also valid because cross-object field updates don’t work with lookup relationships.
Answers are A and D since the cross object field update is only supported on a master-detail relationship, it's worth mentioning that this can be achieved for a lookup relationship using a flow but the question mentions nothing about flows.
