Ans. a. Dermis
Explanation: In dense irregular connective tissue, the collagen fibres are densely packed but are not arranged in parallel bundles (irregular).

The papillary region of dermis is composed of loose areolar connective tissue, but the reticular dermis found under the papillary dermis is composed of densely packed collagen fibers but randomly arranged (not parallel).

Lamina propria is a thin layer of loose areolar connective tissue (not dense) which lies beneath the epithelium in the mucosa.

Tendon and aponeurosis have dense collagen fiber bundles, arranged in a uniform parallel (regular) fashion.
