The following application was developed to allow a user to guess a number between 0 and 10. If a number between 0 and 10 is entered, the number is not accepted.How can this error be removed?

The problem describes a Scratch-like logic issue where a number input between 0 and 10 is not accepted. We will evaluate each proposed fix. Option a: use repeat block instead of repeat until block. This change alters the loop structure but does not address the boundary check. If the program currently repeats until a number is out of range, swapping to a repeat block would not properly validate the 0–10 range and may still reject valid inputs or loop incorrectly. Therefore, this does not fix the underlying condition that filters out valid numbers. Option b: delete say block. Removing a message output does not influence the validation logic that accepts or rejects numbers. The acceptance criteria are determined by the conditional expression, not by what is spoken or displayed. Hence, this change would not resolve the input rejection issue. Option c: change the condition of “number < 0 or number > 10” to "not (number < 0 or number > 10)”. This directly tweaks the validation logic. The original condition rejects any number outside the 0–10 range. Wrapping it with not makes the condition true exactly when the number is within 0–10 (inclusive, if the comparison includes equality). This aligns with the desired behavior of accepting valid inputs and rejecting invalid ones, solving the problem at its core. Option d: change the condition of “number < 0 or number > 10” to “number < 0 and number > 10”. This conjunction is logically impossible for any real number, since a value cannot be both less than 0 and greater than 10 at the same time. As a result, this condition would never be true, potentially causing the program to always reject or always accept depending on how the block is used, but it certainly does not implement correct range checking. Thus, this is incorrect. In summary, the only option that directly fixes the boundary check to allow numbers 0 through 10 while excluding others is option c, since it correctly inverts the range condition to match the intended accepted interval.
