The question asks: In the application shown below what data type is Tall? Begin Input Height If Height > 1.9 Then Tall ← True Else Tall ← False End If Print Tall End

Option A: a. Decimal. A decimal type represents numeric values with fractional components (e.g., 3.14). In the code, Tall is assigned True or False, which are logical boolean values, not numeric decimal values. Therefore Decimal is not a match.

Option B: b. Integer. An integer type holds whole numbers without fractional parts (e.g., 1, 2, -5). The variable Tall does not store numeric counts or whole numbers here; it stores a truth value (true or false) based on a condition. Thus Integer is inappropriate.

Option C: c. Boolean. A Boolean type is used for truth values, typically True/False. The control flow sets Tall to True if Height exceeds 1.9, and otherwise sets Tall to False, which is exactly the behavior of a Boolean variable. This aligns with the standard use of booleans for conditional outcomes.

Option D: d. String. A string type holds text data (e.g., "Tall" or "Yes"). The code does not assign or manipulate text, nor does it store characters forming words. Hence String does not describe Tall.

Putting it together, the only option that matches the behavior—assigning a binary truth value based on a condition—is Boolean, while the other types describe numeric, textual, or non-boolean data, which do not fit this context.
