Sustainable Solutions manufactures three product lines: food containers, outdoor furniture and stationery. Reporting to the CEO are 10 senior managers. Three of the 10 senior managers have responsibility for a product line. Each will assemble and manage teams composed of workers from the Design, Production, Sales and Financial Services departments when a new product is required. This happens often as all three product lines are expanding. This means that at any one time a worker can be reporting to at least two bosses - a team leader and their department manager. This suggests the company's structure is likely to be:

a.none are these choices are correct

b.a functional structure

c.a mechanistic structure

d.a matrix structure

e.an organic structure
