What happens when you clone a Salesforce product?

Answer options:

A.Pricebook entries that you don’t have sharing access to, are not created.
B.If you have read-only access to a field, the value of that field will not carry over to the cloned record.
C.If you have read and write access to a field the value of the field will carry over to the cloned record.
D.All of the above.

Correct Answer: D 
When you clone a Salesforce product, the field that will carry over to the cloned record are only the fields that you have read and write access to. The read-only fields will not carry over. In addition to this, the price book entries that you don’t have sharing access to, are not created.
