Final Answer:
The sign of the result is None, thus the correct option is D.
Step-by-step explanation:
The sign of the result is an important factor to consider when dealing with mathematics. It can tell us whether the result is positive, negative, or neither. In this case, the sign of the result is D. None. This means that the result is neither positive nor negative. It is neither positive nor negative because it is a number without any sign attached to it. This can be seen when a number is written as a fraction, like 3/4 or 5/7, where there is no sign.
In mathematics, a positive sign is typically represented by a plus (+) sign, while a negative sign is represented by a minus (−) sign. A number without any sign is known as a neutral number, and it indicates that the result is neither positive nor negative. For example, if a number is written as 4, it is neutral and does not have a positive or negative sign.
In the given question, the sign of the result is D. None, indicating that the result is neither positive nor negative. This means that the result is a neutral number, and it could be either positive or negative depending on the context. For example, if the result is used in a calculation, it might be positive or negative depending on the other numbers involved in the calculation.
In conclusion, the sign of the result is D. None, meaning that the result is neither positive nor negative. This indicates that the result is a neutral number, and it could be either positive or negative depending on the context in which it is used.
