Given two expressions, exp1 and exp2, which two valid ways return the logical AND of...

The correct answers are A and B .

The original question contains a typing error where 66 should be corrected to the logical AND operator:

& &

A is correct because it first evaluates the logical AND expression and then converts the final result to a Boolean:

Boolean(exp1 & & exp2)

The & & operator returns the first falsy value or the last truthy value. Wrapping the result in Boolean() ensures the final result is strictly either:

true

or:

false

Example:

Boolean( " hello " & & 123);

This returns:

true

B is also correct because it converts both expressions to Boolean values first, then applies logical AND:

Boolean(exp1) & & Boolean(exp2)

This guarantees that both sides of the & & operation are Boolean values.

Example:

Boolean( " hello " ) & & Boolean(123);

This returns:

true

C is incorrect because it uses the bitwise AND operator:

&

This is not the same as logical AND:

& &

Bitwise AND converts values into numbers and compares their binary representation. It does not reliably return a Boolean logical result.

D is incorrect as written because the question gives the expressions as exp1 and exp2, but option D uses var1 and var2. After correction, it would be the same idea as option B.

Therefore, the verified answers are A and B .
