Correct Answers
A. let strValue = String(numValue);

The String function converts the number to a string.
D. let strValue = numValue.toString();

The toString method of the number object converts the number to a string.
E. let strValue = (String)numValue;

This uses the String function in a slightly different syntax, but it still converts the number to a string.
Explanation of Incorrect Options
B. let strValue = * * 4 numValue;

This syntax is incorrect and will result in a syntax error. The * * operator does not exist in JavaScript.
C. let strValue = numValue.toText();

There is no toText method for number objects in JavaScript. The correct method is toString.

B is probably mistyped it should be ""+numValue.
