Is there any scenario in C where it is not feasible to have identical members in a structure and a union? Consider A as a structure and B as a union.Oa$.$ sizeof$($A$)$ is greater than sizeof$($B$)$b$.$ sizeof$($A$)$ is less than to sizeof$($B$)$Oc$.$ sizeof$($A$)$ is equal to sizeof$($B$)$Od$.$ No impact on size
