**Question:**
Decision blocks can be used to control the flow of code based on different outcomes produced by relational blocks. What type of data must relational blocks evaluate to?
**Select one:**
- a. Dictionary
- b. Number
- c. List
- d. Boolean (Selected option)
- e. TinyDB
- f. Text
**Explanation:**
Relational blocks are conditional statements used to compare values and decide the course of action in code. They commonly evaluate to Boolean data types. A Boolean is a binary variable, having only two possible values called "true" and "false." This allows decision blocks to execute particular segments of code based on whether the relational block evaluates to true or false.
For example, a relational block might compare two numbers, and the decision block will then execute pieces of code depending on whether the comparison is true or false. This is fundamental for building logical flows and conditional operations in programming.
