The TRUNC function truncates a number to a specified number of decimal places without rounding. TRUNC(12.3456, 3) keeps only the first 3 decimal places, resulting in 12.345. Option C (12.346) would be the result if rounding occurred, but truncation simply discards extra digits.

AI explanation

To answer this question, you need to understand the TRUNC function.

The TRUNC function is used to truncate a number to a specified number of decimal places. It removes all decimal places beyond the specified number without rounding the number.

In this case, the TRUNC(12.3456, 3) means truncating the number 12.3456 to 3 decimal places.

Let's evaluate each option:

Option A) 12.3 - This option is incorrect because it only has one decimal place, while the TRUNC function truncates the number to 3 decimal places.

Option B) 12.3000 - This option is incorrect because it has four decimal places, while the TRUNC function truncates the number to 3 decimal places.

Option C) 12.346 - This option is incorrect because it has three decimal places, while the TRUNC function truncates the number to 3 decimal places and removes the decimal places beyond that.

Option D) 12.345 - This option is correct because it has three decimal places, which matches the result of the TRUNC(12.3456, 3) function.

Therefore, the correct answer is D) 12.345.
