i didn't read the concept related to strongly connected components please it describe it for this question

4 SCC

and after adding edge SCC become 2
i think option (d) is correct counter example for statement (2) is consider the graph ABCD where path can be given as

$A\rightarrow B ,B\rightarrow C, C\rightarrow D ,A\rightarrow D$ now here there is zero strongly connected component but when we add an edge $C\rightarrow A$ there will be one strongly connected component i.e ABC.
