Answer:
The answer to this question is given below in the explanation section.
Explanation:
The value stored by a variable can be changed after it is assigned(true).
The value of a variable can be changed after it is assigned, for example:
int a=10;
and we can change the value of variable a in letter program such as:
a=15;
Variables are a name for a spot in the computer's memory (true).
it is true, because the variables value stored in the computer's memory and we can access theses values by their name (variable name). so Variables are a name for a spot in the computer's memory.
Variable names can be words: such as temperature or height (true).
Yes, the variable name can be words such as height, width, temperature etc.
The value stored by a variable cannot be changed after it is assigned (false).
It is noted that the value stored by a variable can be changed after it is assigned. However, it is noted that is some programming language, you can't change the value of static variable.

Answer:
a) range check
Explanation:
Validation can be defined as an automatic computer check that is designed to ensure any data entered is sensible, consistent, feasible and reasonable.
Basically, there are five (5) main validation methods and these includes;
I. Presence check: checks that the user enters (inputs) data into the field. It ensures a field isn't accidentally left blank.
II. Length check: checks that the data entered isn't too short or too long. It ensures that the data meets the minimum characters.
III. Type check: checks that the data entered is in the right format. For example, string, integer, float, etc.
IV. Check digit: checks that the digit entered is acceptable and consistent with the rest of the digits.
V. Range check: checks that the data entered is between the accepted lower (minimum) and upper (maximum) level.
Hence, range check is a validation type you would use to check that numbers fell within a certain range.
For example, 0 < x > 1000 is a range check.
