c. 3461
d. None of the above

Answer 1

The error in the multiplication is that the student incorrectly added the numbers. The correct answer is d) none of the above.

Step-by-step explanation:

To find the answer, we first need to calculate 346 times 28, which is 9,688. Then, we need to add 9,688 to 692. The sum is 10,380.

The error in the given multiplication is that the student incorrectly added 692 to 2,768 instead of 9,688. So, the correct answer is none of the above (d).
