What will be the output of the following code snippet? //IMG//

Selected Answer: C Let's analyze this code step by step: d = {} creates an empty dictionary. d[1] = 1 adds a key-value pair where the key is the integer 1 and the value is 1. d['1'] = 2 adds another key-value pair where the key is the string '1' and the value is 2. d[1] += 1 increments the value associated with the key 1. So now d[1] becomes 2. sum = 0 initializes a variable sum to 0. The for loop for k in d: iterates over the keys in the dictionary. In each iteration, it adds the value associated with the current key to sum. After the loop, sum will contain: 2 (from d[1]) 2 (from d['1']) Therefore, the final value of sum will be 4. print(sum) will output this final value. So, the output of this code will be: 4
