Given the following code snippet:  int n = 172;  n = bar(n);Which of the following is the matching function definition?Question 9Answera.float bar(float i) {  float value = (i*PI)/180.0;  return value;}b.int bar(int a) {  int rem = a%60;  return rem;}c.boolean bar(int n, int m) {  int div = n/m;  return (div*m == n);}d.void bar(float a, float b) {  float scale = a * b;  ellipse(400, 400, scale, scale);}

What is the output of the following code snippet? int main()    {        float f1 = 0.1;        if (f1 == 0.1)            printf("equal\n");        else            printf("not equal\n");    }a.equalb.not equalc.output depends on the compilerd.error

Consider the following code (which does not do anything significant)int h(int p) {    return p++;}int g(int x, int y) {    int z;   return h(y);}int f(int a, int b) {    if(a % 3 == 0) {        g(a, 2);        } else {        h(a);    }       return 10;}int main() {    int m;    scanf("%d", &m);    if(m % 2 == 0) {        f(m, 20);    } else {        g(20, m);    }       return 0;   }How many functions can be active the same time, in the execution of the above program?
