the correct answers are:
A. Boolean(var1) && Boolean(var2)
B. Boolean(var1 && var2)

Explaintion:
A. Boolean(var1) && Boolean(var2)

This approach explicitly converts var1 and var2 to Boolean values using the Boolean() function before applying the logical AND operation. This ensures that the result is always a Boolean value.

B. Boolean(var1 && var2)

This approach first evaluates the logical AND of var1 and var2, which results in either the value of var1 if var2 is truthy, or the value of var2 if var1 is falsy. Then, the Boolean() function is used to convert the result to a Boolean value.

Explanation of why other options are not valid:

C. var1.toBoolean() && var2.toBoolean()

toBoolean() is not a standard JavaScript method. This will result in an error as toBoolean() does not exist on standard JavaScript objects.

D. var1 && var2

This will return the value of var1 if var1 is falsy, otherwise it returns the value of var2. It does not ensure that the result is explicitly a Boolean value....

Correct Answers are A & D
