Correct Answer: the balancing of the force of demand and supply for the commodity.

Solution : The correct option is the balancing of the force of demand and supply for the commodity .

The market reaches equilibrium at the intersection of the demand and supply curves, where the quantity demanded matches the quantity supplied. This is the point of market balance, where neither a surplus nor a shortage of the commodity exists. Any shifts in either the demand or supply curves will result in adjustments to the equilibrium price and quantity.
