A)massively folded metamorphic rock units with structures that resemble putty
B)faults which juxtapose vastly different rock types like deep lower crustal granites and fluvial deposits containing coal beds
C)extensive, flat lying younger beds disconformably overlying older strata
D)extinct marine fossils found thousands of metres above sea level in tilted strata in the mountains

Extensive, flat lying younger beds disconformably overlying older strata do not indicate any tectonic forces or structural deformation. It simply means that sedimentation occurred over a relatively long period of time, with periods of erosion or non-deposition in between, resulting in a horizontal contact between the two rock layers. The other options all indicate evidence of tectonic forces and structural deformation.
