Final answer:
The absolute value of -14 is 14, reflecting the non-negative distance from zero on the number line.
Step-by-step explanation:
The absolute value of a number is the distance of that number from zero on the number line, regardless of the direction. Since distance cannot be negative, the absolute value of a negative number is always positive. Therefore, the absolute value of -14 is 14, which corresponds to option (a) 14.
