What type of stress causes an anticline? compression. tension. shear. force.

Compression.

Explanation:

The anticline is a type of fold that is in an arch shape and is in the convex form with the crust is located with the max curvature and limbs are the side of the folds that dip away. The uplifted core part of the fold causes the compression of the strata that preferential erode to a deeper upper thrust fold that leads to the crustal deformations. This motion along the fault induces the extension and the shortening of the plates and deforms the strata of the fault.
