can have only positive values
does not exist
is always less than 1010
can have only negative values E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is: A. can have only positive values.
An unsigned double type of data can have only positive values. It is a 64-bit data type that can store a value between 0 and 2^63-1.
Option B is incorrect because unsigned double type of data does exist.
Option C is incorrect because unsigned double type of data is not always less than 1010. It can store a value between 0 and 2^63-1, which is much larger than 1010.
Option D is incorrect because unsigned double type of data can have positive values.
Option E is the correct answer because it is the only option that is not contradicted by the other options.
