b = {4: "D", 5: "E"} 
a.update(b) 
print(a)

{1: 'A', 2: 'B', 3: 'C'}

{1: 'A', 2: 'B', 3: 'C', 4: 'D', 5: 'E'}

Error

{4: 'D', 5: 'E'}

Explanation

The output will be:

(B) {1: 'A', 2: 'B', 3: 'C', 4: 'D', 5: 'E'}

Explanation:

The update() method adds key-value pairs from dictionary b into dictionary a.
After calling a.update(b), the dictionary a will now include the key-value pairs from b. So, the updated dictionary a will be {1: 'A', 2: 'B', 3: 'C', 4: 'D', 5: 'E'}.

Correct Answer: B) {1: 'A', 2: 'B', 3: 'C', 4: 'D', 5: 'E'}
