Which sentence correctly describes a characteristic of a CPU? Select the correct

#include <stdio.h>

#include <time.h>

int main()

{

clock_t start, end;

double cpu_time_used;

//starting the cpu clock.

start = clock();

for(int i=0; i<10000; i++){

my_func_with_only_subscript();    

}

// closing the cpu clock.

end = clock();

// calculating time elapsed in secs.

cpu_time_used = ((double) (end - start)) / CLOCKS_PER_SEC;

printf("Time taken with subscript references::%f\n",cpu_time_used);

// starting the cpu clock

start = clock();

for(int i=0; i<10000; i++){

my_func_with_pointers();

}

// closing the cpu clock.

end = clock();

// calculating the time elapsed in array reference through pointers.

cpu_time_used = ((double) (end - start)) / CLOCKS_PER_SEC;

printf("Time taken with pointers::%f\n",cpu_time_used);

return 0;

}

// function to reference the 2D array through subscripts.

void my_func_with_only_subscript()

{ //assuming that the usage of

int arr[15][5] = {0}; //square matrice is not mandatory

for(int j=0; j<5 ; j++){

for(int i=0; i<15; i++){

}

}

return;

}

// function to reference the 2D array through pointers.

void my_func_with_pointers()

{ //assuming that the usage of

int arr[15][5] = {0}; //square matrice is not mandatory
