How many times is the function linear_search() called when the following code is executed?

[answerhappygod]

#include<stdio.h>
#include<stdlib.h>
struct Node
{
int val;
struct Node* next;
}*head;
int linear_search(struct Node *temp,int value)
{
if(temp == 0)
return 0;
if(temp->val == value)
return 1;
return linear_search(temp->next, value);
}
int main()
{
int arr[6] = {1,2,3,4,5,6};
int n = 6,i;
head = (struct Node*)malloc(sizeof(struct Node));
head->next = 0;
struct Node *temp;
temp = head;
for(i=0; i<n; i++)
{
struct Node *newNode = (struct Node*)malloc(sizeof(struct Node));
newNode->next = 0;
newNode->val = arr;
temp->next = newNode;
temp = temp->next;
}
int ans = linear_search(head->next,6);
if(ans == 1)
printf("Found");
else
printf("Not found");
return 0;
}
a) 5
b) 6
c) 7
