Answer
RollNumberSNameSDateofBirthGUID
1Atharv2003-05-1512354899
2Sudha2002-02-28NULL

Reason — In the above code, a new row is inserted into the 'Student' table, values are provided for RollNumber, SName, and SDateofBirth, but not for GUID. Since GUID is not specified, it will take on its default value, which may be NULL if no default value is defined for the column.
