The correct answer is - hot and dry.
The CT air masses are air masses that originate from deep inside the land masses in the tropical regions of the Earth. The ''C'' actually stands for continental, thus indicating the formation of the air mass over a land mass, while the ''T'' stands for tropical, thus indicating the tropical region of where the land mass over which this air mass forms.
Because these air masses form over land in the tropics, they are hot and dry. The hot and dry characteristics come from the bigger heating of the land masses, as well as the lack of water vapor over the land masses.

Answer:
Alright.
Explanation:
<em>'2D and 3D refer to the actual dimensions in a computer workspace. 2D is "flat", using the horizontal and vertical (X and Y) dimensions, the image has only two dimensions and if turned to the side becomes a line. 3D adds the depth (Z) dimension.'</em>
Basically, 2D maps are flat (like paper), and 3D maps are not (like a globe).
