An increase in the price of the commodity does not cause an increase in market supply. In fact, it's the opposite. An increase in theprice of a commodity can lead to an increase in the quantity supplied (as suppliers are willing to supply more at higher prices),but it does not shift the supply curve or increase market supply. The other options (improvement in innovation and technology,reduction in the cost of raw materials, and favourable weather conditions) can all lead to an increase in market supply.
