To answer this question, we need to understand the concept of signed data types.
In computer programming, a signed data type is a data type that can represent both positive and negative values. It uses a sign bit to indicate the sign of the value. The sign bit is typically the leftmost bit in the binary representation of the number.
For example, in a signed 8-bit data type, the range of values is from -128 to 127. The sign bit (the most significant bit) is 0 for positive numbers and 1 for negative numbers.
Now, let's consider the statement: "A signed data type has an equal number of non-zero positive and negative values available."
This statement is true. In a signed data type, the number of positive values is equal to the number of negative values. This is because the sign bit can represent one of two values (0 or 1), which determines whether the number is positive or negative.
Therefore, the correct answer is A) True.
