c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
