Explanation:

This question tests the ability of the student to convert a 3D model to wedge-dash notation.

The difficulty is low as the shape of the model is close to that of the 2D representation – no rotation around the single bonds is needed to determine the relative orientations of the substituent groups.

Carbon-1 is attached to an H-atom coming out of the page (wedge bond), an $NH_2$​ group going into the page (dashed bond), and a $CH_3$​ group in the plane of the page.

Carbon-2 is attached to a $Cl$ atom coming out of the page (wedge bond), an H atom going into the page (dashed bond), and a $CH_3$​ group in the plane of the page.
