$0.$ In a competition, four different functions are observed. All the functions use a single for loop and within the for loop, same set of statements are executed. Consider the following for loops:$($A$)$ for$($i $=0$; i $<$ n; i$++)($B$)$ for$($i $=0$; i $<$ n; i $+=2)($C$)$ for$($i $=1$; i $<$ n; i $*=2)($D$)$ for$($i $=$ n; i $<=$ n; i $/=2)$If n is the size of input $($positive$),$ which function is most efficient $($if the task to be performed is no
