A method is passed a list of generic sObjects as a parameter.

What should the developer do to determine which object type (Account, Lead, or Contact, for example) to cast each sObject?

A. Use a try-catch construct to cast the sObject into one of the three sObject types.
B. Use the getSObjectName method on the sObject class to get the sObject name.
C. Use the first three characters of the sObject ID to determine the sObject type.

D. Use the getSObjectType method on each generic sObject to retrieve the sObject token.
