Consider the given relational schema: Suppliers(sid:integer, sname:string, city:string, street:string) Parts(pid:integer, pname:string, color:string) Catalog(sid:integer, pid:integer, cost:real) Assume that, in the supplier's relation above, each supplier and each street within a city has a unique name, and (sname, city) forms a candidate key. No other functional dependencies are implied other than those implied by primary and candidate keys. Which one of the following is TRUE about the above schema? O The schema is in 2NF but not in 3NE O The schema is in 3NF but not in BCNF O The schema is in BCNF Save Answer Q2 Normal form The relational schema for Student Performance of a course (s_name, c_No, s_id, grade) has the following functional dependencies: s_name, c_No + grade sid, c_No + grade s_name - s_id s_id s_name The highest normal form of this relation scheme is О ВCNF O 2NF О 3NF
