The correct response is:

Albert forgot to carry a ten over to the next column of digits.

When adding 346 and 51, Albert should have aligned the digits properly and accounted for carrying over when the sum of the digits in a column exceeds 10.

The correct answer is:

Albert forgot to carry a ten over to the next column of digits.

When adding 346 and 51, the correct addition should result in 397, but Albert incorrectly wrote 856, indicating a mistake in the addition process, particularly with carrying over.
