Solution
The correct option is A Fibroblasts
Collagen is the most common fibrous protein in the ECM and is important for resisting tensile forces. It is the most abundant protein in mammals - 25% of total protein mass. It is a protein composed primarily of the amino acids glycine & proline, and it also contains sugar groups.It is secreted by fibroblasts as procollagen, and amino acid residues at the ends of the protein are cleaved off outside the cell to form collagen, which then aggregates into fibres. Therefore, the correct answer is 'Fibroblasts'.
