  4. None of the above


Correct Option: A
  1. True

  2. False


Correct Option: B
Explanation:

To solve this question, the user needs to know the basic concept of signed data types.

A signed data type is a data type that can represent both positive and negative numbers. This type of data is represented using a sign bit, which indicates whether the number is positive or negative.

Now, let's go through each option and explain why it is right or wrong:

A. True: This option is incorrect. The number of non-zero positive values and negative values in a signed data type is not equal. In a signed data type, one bit is reserved for the sign, which means there is one less bit for the magnitude. As a result, the range of positive values is one less than the range of negative values. For example, in a signed 8-bit data type, the range of positive values is 0 to 127, while the range of negative values is -1 to -128.

B. False: This option is correct. A signed data type does not have an equal number of non-zero positive and negative values available. As explained above, the range of positive values is one less than the range of negative values in a signed data type.

Therefore, the answer is: B. False.
