What will be the shape of the PPC in the table below?

Straight line

the correct answer is Option 3: Straight line

The table provided shows that as production of Good A increases by a constant amount (10 units), the production of Good B decreases by an equal amount (10 units). This indicates a constant opportunity cost for producing both goods, meaning that the economy gives up the same quantity of Good B to produce an additional quantity of Good A at every point.

In such a case, the Production Possibility Curve (PPC) would be a straight line, reflecting constant opportunity costs.
