Refer to figure. 
The cross-section shown in (1) _____ and the vertical pressure structure in (2) _____ represent a cold occlusion.

  • A

    (1) Figure 3; (2) Figure 5.

  • B

    (1) Figure 4; (2) Figure 5.

  • C

    (1) Figure 4; (2) Figure 6.

  • D

    (1) Figure 3; (2) Figure 6.

Refer to figure.
In a cold occlusion, the air behind the cold front is colder than the air ahead of the warm front.

When the fronts meet in a cold occlusion, the cold front slips underneath the warm front (the cold front forces the warm front up). This is seen in figure 3.

Pressure decreases more rapidly with altitude in cold air than in warm air. Thus, figure 5 indicates that the air behind the cold front is colder than the air ahead of the warm front.
