The following method is taking two string parameters and is retuming the number of occurrences of the it itst string $($the parameter word$)$ into the second $($the parameter text$).$

public static int int count $=0$;

int $i=$ text. indexof$($word$)$;

while

count$+$t;

text $\frac{?}{*}=*$ missing code $*\frac{*}{?}$

$\}$

$i=$ text. indexof$($word$)$;

$\}$

return count;

For example, the call countoccurrences$("$is$",$ "This is history"$)$ returns the value $3.$ Which of the following lines can replace the $\frac{?}{?}**$ missing code $*\frac{*}{5}$ such that the program works as intended? intended?

$($A$)$ word.substring$($i$)$;

$($B$)$ word.substring$($text$)$;

$($C$)$ text.substring$($i $+$ word. length $()$
