Question 1

“x1 is a clone of x” means x1 is identical to x in terms of the physical attributes namely, height, weight and complexion. Given, height, weight and complexion only form a complete set of attributes for an entity, cloning is an equivalence relation. What is your impression about this statement ?
The statement is true


The statement is false


The truth value of the statement cannot be computed


None of these

Question 1 Explanation:
The given statement says that the Relation R contains x and x1 which are identical. Which means (x,x1) are same as (x,x).
We know that ” a relation of (x,x) type is an equivalence as it satisfies Reflexive, symmetric, transitive.
The answer would be option A, it is equivalence.
