1a. Assume that the language in the below program is stack-based and parameter passing is by value-result. Draw the activation record for procedure Fourth and label the parts of the activation record. 1b. Using your activation record, explain how the variables in L ine L(C:=A+Yi) will be accessed at run time. 1c. Using your activation record, explain the exception handler for the exception in Fourth will be accessed at run time. program First \{ varA,B : integer, A=B=1.0 procedure Second \{ var B, C: integer, B=C=2; try Call Third( C, B); catch Exception \& print("Error"); )/I Second procedure Third(X,Y : integer ){ var D : integer, D=3; Call Fourth (X+Y,D); \}/TThird procedure Fourth (X,Y : integer ){ varC integer; C:=A+Y; -Line L if C
