Answer 1

(there are more than 1 different questions, as per policy i am answering first question)

question 1 :

feasible region is the region in which all of the constraints hold true

therefore,

it can be a polygon but there shoud be atleast three constraints in that case

the feasible region can be a point if only one combination of the two variables fulfills the given constraints

it can be nonexistent if there is no combination of the two variables that satisfies all constraints

therefore all of the above are possible

therefore,

answer : option D : any of the above
