How do you initialize an array in C?a.int arr[3] = (1,2,3);b.int arr(3) = {1,2,3};c.int arr[3] = {1,2,3};d.int arr(3) = (1,2,3);

The correct way to initialize an array in C is option c. Here's how you do it:

1. Declare the array with a specific size. In this case, the size is 3. So, you write int arr[3].

2. Initialize the array with specific values. In this case, the values are 1, 2, and 3. So, you write = {1,2,3};.

3. Put it all together. So, the final code is int arr[3] = {1,2,3};.

The other options are incorrect because they either use parentheses instead of square brackets, which is not the correct syntax for declaring an array in C, or they use parentheses instead of curly braces, which is not the correct syntax for initializing an array in C.
