Question:-
The following program is to be tested for statement coverage:

begin

if (a == b) {S1; exit;}

else if (c == d) {S2;}

else {S3; exit;}

S4;

End

The test cases T1, T2, T3 and T4 given below are expressed in terms of the
properties satisfied by the values of variables a, b, c and d. The exact values are not given.

T1 : a, b, c and d are all equal

T2 : a, b, c and d are all distinct

T3 : a=b and c !=d

T4 : a !=b and c=d

Which of the test suites given below ensures coverage of statements S1, S2, S3 and S4?
Option (A)
T1, T2, T3
Option (B)
T2, T4
Option(C)
T3, T4
Option(D)
T1, T2, T4
