a. parentheses
b. square brackets
c. curly braces
d. angle brackets

Answer 1

To execute more than one action within an if statement, a pair of curly braces { } is used to define a block of code.

Step-by-step explanation:

If you want to take more than one action following the evaluation of a Boolean expression within an if statement, you use a pair of curly braces { } to place the dependent statements within a block. The correct answer to the question is: c. curly braces. In many programming languages, including Java, C++, and JavaScript, curly braces are used to define the beginning and end of a block of code that is meant to be executed if the Boolean expression within the if statement evaluates to true. Without curly braces, only the first statement after the if condition is considered part of the if statement. For example:

if (condition) {
action1();
action2();
}
else {
action3();
}

In this example, action1() and action2() are both executed if the condition is true, because they are enclosed within curly braces.
