The advantages derived from the efficient combination of factors of production in agriculture include the following except

The answer is "increased production cost". Efficient combination of factors of production in agriculture refers to the optimal use of resources such as land, labor, and capital to achieve the highest level of output. This results in lower production costs, increased profit margins, and higher gross revenue. However, increased production costs would mean that the optimal use of resources has not been achieved, which would lead to lower profit margins and gross revenue. Therefore, increased production costs are not an advantage of efficient combination of factors of production in agriculture.
