Every integer less than 0 has the sign.
A.\[ + \]
B.\[ - \]
C.\[ \times \]
D.\[ \div \]

Hint: Here we have to determine the sign of the integers that are less than zero. An integer is defined as a number that is not fractional and non-decimal. Here we will use the number line to determine the sign of the integers.

Complete step-by-step answer:
We know that the integers can be both positive and negative.
Integer Includes the counting numbers like 1, 2, 3, …. , zero and the negative of the counting numbers like \[ - 1, - 2, - 3\]….
First we will draw the number line including all the integers.




We know that in number lines, the numbers which are on the left sides of 0 are smaller than the numbers which are on the right sides. Here we have to determine the sign of numbers less than zero. So, the numbers must lie on the left side of zero on the number line. We can observe that all the numbers less than zero are negative numbers or negative integers i.e. the numbers that have negative sign.
The numbers less than zero are \[ - 1, - 2, - 3\] ……
Therefore, the integers less than zero have negative signs.
Hence, the correct option is option B.

Note: Integer values are any numbers that are whole numbers. They are defined as being rationally real numbers without containing any fractional components. Integers can be negative or positive but they can’t be fractional or decimal numbers. For example: \[- 179, 4, 27, -51, -78\] … are all integers. There is an infinite number of integers because the number line is infinitely long in both the positive and negative directions.
