Correct Answer

Explanation

In JavaScript, the + operator can be used to concatenate strings.
In this case, the + operator is used to concatenate the string "Hello" with the number 10
Since one of the operands is a string, the + operator will treat both operands as strings and perform string concatenation.
The result will be the string "Hello10"
