The Cyclomatic complexity of each of the module $$A$$ & $$B$$ shown below is $$10.$$ What is the cyclomatic complexity of the sequential integration show on the right hand side?

What is the appropriate pairing of items in the two columns using listing various activities encountered in a software use cycle?

The following program is to be tested for statement coverage:
begin
if $$\left( {a = \,\, = b} \right)\,\,\left\{ {S1;\,\,exit;} \right\}$$
else if $$\left( {c = \,\, = d} \right)\,\,\left\{ {S2;} \right\}$$
else $$\left\{ {S3;\,\,exit;} \right\}$$
$$S4;$$
end

The test cases $${T_1},\,{T_2},\,{T_3}\,\,\& \,{T_4}$$ 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.
$${T_1}:\,a,\,b,\,c\,\& \,d$$ are all equal
$${T_2}:\,a,\,b,\,c\,\& \,d$$ are all distinct
$${T_3}:\,a = b\,\,\,\& \,\,\,\,c\,!\, = \,d$$
$${T_4}:\,a! = b\,\,\,\& \,\,\,\,c\, = \,d$$

Which of the test suites given below ensures coverage of statements $${S_1},\,{S_2},\,{S_3}\,\,\& \,{S_4}$$ ?
