which of the following statements is true with regard to best operating level? group of answer choices in underutilization, average unit cost of output increases in overutilization, average unit cost of output increases best operating level is the minimum average unit cost of output best operating level is the denominator of capacity utilization calculations all of these answers are true

With reference to the solutions, following things may be noted1) homogeneous solutions comprises of single phase.2) heterogeneous solution comprises of more than one phase.3) in colloidal solution, solute is evenly distributed in solvent. in such system, it is difficult to separate solute and solvent.4) in suspension, there is an uneven distribution of solute in solvent. in such system, solute and solvent gets separated on standing long.    blood is a homogeneous and colloidal solution,salad dressing is a heterogeneous and suspension solution.
