Final answer:
To find the value of 'result', we first add 28 and 4 to get 32, then divide by 2 to get 16 as the final answer.
Step-by-step explanation:
The value of result in the given expression result = (28 + 4) / 2 can be calculated by first adding the numbers inside the parentheses and then dividing the sum by 2. So, we first calculate 28 + 4 which equals 32. Next, we divide 32 by 2, which gives us 16. Therefore, the correct answer is b) 16.
