Q: The number of values that a method can return is:  

In most programming languages, a method can return only one value at a time. Therefore, the correct answer is (a) 1. When you define a method and specify a return type, you are indicating the type of value that the method will return. The method can perform computations, process data, and then provide a single result of the specified type.

For example, in Java, a method declaration might look like this:

public int add(int a, int b) {
    return a + b;
}

In this example, the add method takes two integer parameters (a and b) and returns a single integer result, which is the sum of a and b. The method specifies int as the return type, indicating that it will return an integer value.

If a method needs to return multiple values, one common approach is to use other data structures like arrays, objects, or collections to bundle and return multiple values within a single container.
