Consider a relation schema R = (A, B, C). For each part below (note that each part is separate), supply a relation (table) T on R having just four rows and satisfying the given functional dependency (or dependencies) but NOT satisfying any other functional dependencies except trivial ones and those that are derivable from the given one(s). The values of the attributes in your rows should be lower-case letters with subscripts (e.g. a₁, b₃, c₂).

a. A -> BC, B -> C

b. A -> BC

c. AB -> C
