Answer: b) 15

Explanation: The reduce() method executes a provided function for each value of an array, and returns a single value. In this case, the provided function calculates the sum of all the numbers in the array by adding each number to the total.
The initial value of the total parameter is not specified, so it defaults to the first value in the array (1).
Therefore, the sum of the array is calculated as (1 + 2 + 3 + 4 + 5), which is equal to 15.
