TRUE or FALSE
 A True B False C Either A or B D None of the above
Explanation:

Detailed explanation-1: -Boolean values and operations Constant true is 1 and constant false is 0. It is considered good practice, though, to write true and false in your program for boolean values rather than 1 and 0. The following table shows comparisons and boolean operations.

Detailed explanation-2: -Let’s look at how the AND operator works. There are two AND operators in R, & and && . Both operators work similarly, if the right and left operands of AND are both TRUE the entire expression is TRUE, otherwise it is FALSE. For example, TRUE & TRUE evaluates to TRUE.

Detailed explanation-3: -There are only two boolean values. They are True and False . Capitalization is important, since true and false are not boolean values (remember Python is case sensitive).

Detailed explanation-4: -The true operator returns the bool value true to indicate that its operand is definitely true. The false operator returns the bool value true to indicate that its operand is definitely false. The true and false operators aren’t guaranteed to complement each other.

Detailed explanation-5: -What does true or false mean? True or false is variously said of something that must be considered as correct (true) or incorrect (false).
