Suppose that Si and S2 are empty stacks and al, a2 and a3 are objects. What do the stacks contain after executing the following sequence of operations? s1.push(a2), Si.push(al), S2.push(a3); S2.push(S1.pop(), S2.push(S1.peek(). Select one: O A. SI= [a2, al ] and S2-la,3,a3, al] O B. S1-la2) and S2-[a3 al, a2] O C. S1-11 and 52-la,3, al] O D. S1=1) and S2-11 Data abstraction: the separation of data type's properties from its + Select one: O a. logical implementation O b. operation, task O c. Not logical implementation O d. data type data structure
