Consider the join of Relation R with a relation S. If R has m tuples and S has n tuples, then the maximum and minimum size of the join respectively are:Am+n and m-nBM+n and 0Cmn and m+nDmn and 0

Consider two database relations T1 and T2 having 5 and 2 tuples respectively. What is the maximum number of tuples that could appear in the natural join of R and S?a.2b.10c.5d.7

Consider two relations R and S where R has 4 tuples and S has 2 tuples. The natural join of R and S will have at most 4 tuples.Question 5Select one:TrueFalse

Consider the following relation schema pertaining to a training database:Trainee (traineeno, name, address)Enroll (traineeno, courseno, coursename)where the primary keys are shown underlined. The number of tuples in the Trainee and Enroll tables are 60 and 10 respectively. What are the maximum and minimum number of tuples that can be present in (Student * Enroll), where ‘*’ denotes inner join ?

Suppose now that R(A,B) and S(A,B) are two relations with r and s tuples, respectively (again, not necessarily distinct). If m is the number of (not necessarily distinct) tuples in the result of the SQL query:R intersect S;Then which of the following is the most restrictive, correct condition on the value of m?0 <= m <= min(r,s)min(r,s) <= m <= max(r,s)0 <= m <= r + sm = min(r,s)
